Finally, we are ready to make the switch to OpenJDK 7 as the defaultJava compiler.Next week, we will upload version 0.49 of java-common which willswitch the default to OpenJDK 7. That means that all packages dependingon default-jdk and default-jre ... [More] will use the OpenJDK 7 for the supportedarchitectures.However, since some architectures (sparc, s390, mips, mipsel,partially kfreebsd) are not supported by the current package of OpenJDK7, these architectures will remain with OpenJDK 6 as default. Volunteersare welcome.Sylvestre Ledru, in an e-mail announcement on the behalf of the Debian Java packaging team. [Less]

JogAmp Ji Gong project announcement “Ji Gong shall enable the VM technology across platform and devices.” Sven Gothel Aug 04, 2013; 9:45am ” Bug 790 <https://jogamp.org/bugzilla/show_bug.cgi?id=790> Bug 698 ... [More] <https://jogamp.org/bugzilla/show_bug.cgi?id=698> +++ Current Ji Gong Dependency including the OpenJDK API subset, etc: <https://jogamp.org/bugzilla/showdependencytree.cgi?id=790&hide_resolved=1> +++ 1st Milestone – Core JRT for all platforms .. <https://jogamp.org/bugzilla/show_bug.cgi?id=791> <https://jogamp.org/bugzilla/show_bug.cgi?id=792> Calling for volunteers. We are looking for sponsors! +++ Preface ======== OpenJDK and its chair decided not to go mobile?Bug 698 was written due to the “Fear, uncertainty and doubt” (FUD) strategy of Oracle of not giving express permission to use OpenJDK in compliance w/ the 4 freedoms of software (FSF definition). On the contrary, Oracle gives a patent grant for using OpenJDK for desktop only, implying mobile use may be prohibited. This implication is highly likely non-sense, especially in the light of the latest Oracle vs Google case where Oracle was not able to substantiate a patent infringement by Google’s Dalvik VM. However .. the current situation lacks of: – OpenJDK builds for Windows, OSX, Android, .. – IcedTea-Web builds for Windows, OSX, Android, .. As Xerxes put it: The horse is bound to a chair and is not running .. Project Name ============ Ji Gong <https://en.wikipedia.org/wiki/Ji_Gong> “Unlike a traditional Buddhist monk, Daoji did not like following traditional monastic codes. Daoji had a penchant for openly eating meat and drinking wine; his robes were often tattered and dirty from travelling from place to place, and stumbling while intoxicated. However, Daoji was kind hearted and was always ready to lend a helping hand to ordinary people. He would often treat the sick and fight against injustice. The monks, bewildered and fed up with his behavior, expelled Daoji from the monastery. From then on, Daoji roamed the streets and helped people whenever he could.” Hence Daoji does people good while not necessarily conforming to certain arbitrary rules, while maintaining sanity and being kind hearted. The character is quite popular in the Asian culture. Project Spirit ============== This project shall match the kind direction of it’s name giving character, while also serving w/ JogAmp’s goals of being a technology enabler. Ji Gong shall enable the VM technology across platform and devices. This project must not necessarily being maintained by the JogAmp community. On the contrary .. we would prefer this effort to be done from the original authors, i.e. OpenJDK and IcedTea-Web. However, until the goals below and this spirit of a free solution is being picked up, we may continue pushing it forward from here. Note: Bug 698 sadly wasn’t being replied to by neither Oracle nor the OpenJDK team. Of course, no surprise here, since for Oracle it might be a conflict of interest due to their ‘goals’ to market their ARM hotspot proprietary solution and the OpenJDK team consist mainly of Oracle and RedHat members. The latter focuses on server solutions and is highly cooperating w/ Oracle. Project Goal ============ - Availability of the GPLv2 based OpenJDK runtime environment (JRT/JVM) – Desktop (Linux, Windows, OSX, ..) – Mobile (Android, other phones and tablet OS [maybe even iOS]) – VM CPU support: – Intel/AMD 32bit and 64bit – ARM based CPUs [Hotspot client/server n/a at time of writing. May need to use JamVM or AvianVM, ..] - Optional AWT/Swing/etc – maybe added at a later time - Web Plugin based on IcedTea-Web (JWeb) – Capable to run w/o AWT using a pluggable windowing subsystem implementation – Optional AWT/Swing/etc – maybe added at a later time +++ ” Quoted from: JogAmp forum: Project: Ji Gong http://forum.jogamp.org/Project-Ji-Gong-td4029738.html [Less]

In Reaching for the Web, I spoke about the SVGGraphics2D implementation I've been working on. Well, I've taken this thing about as far as I can without getting some real-world feedback on it, so I've packaged it up in a new project JFreeGraphics2D ... [More] and released it. It's taken slightly longer than I planned, because along the way I wondered what it would take to do a PDFGraphics2D implementation and somehow could not put it down. So JFreeGraphics2D 1.0 supports PDF as well as SVG and includes the following key components: SVGGraphics2D PDFDocument and PDFGraphics2D CanvasGraphics2D An important feature of the library is that it is small, the jar file is just 88kB for PDF and SVG with no external dependencies. I've tested it using JFreeChart and it is working well, but it is definitely going to benefit from some broader usage (especially since JFreeChart doesn't touch all the corners of the Java2D API). Please try it out and send your feedback. On the license... JFreeGraphics2D is dual licensed, free under the terms of the GNU Affero General Public Licence plus you can purchase a proprietary license if you are not yet ready for Free Software. Initially the proprietary licenses will be bundled with the JFreeChart Developer Guide and Demo Source Code, to encourage companies to support our work more than just in spirit. Tweet [Less]

The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as a PulseAudio sound driver and support for alternative virtual machines. This release updates our ... [More] OpenJDK 7 support to include support for the ARM32 JIT port running on HotSpot 23, meaning ARM users can move to the 2.3.x series. A number of build issues were discovered with the ARM port in the previous 2.3.11 release and this release provides fixes for these. In addition, IcedTea includes the usual IcedTea patches to allow builds against system libraries and to support more esoteric architectures. In this release, use of the system version of LCMS is again enabled by default, but requires version 2.5 or above. If you find an issue with the release, please report it to our bug database under the appropriate component. Development discussion takes place on the distro-pkg-dev OpenJDK mailing list and patches are always welcome. Full details of the release can be found below. What’s New? New in release 2.3.12 (2013-07-26) ARM Port Set Zero flags for ARM32 in jdk_generic_profile.sh Tell gcc explicitly that the bytecodes_arm.def input from stdin is C++, allowing C++ flags to be used.

At work I make heavy use of the GNU Emacs mode serial-term to interface with various target boards. The boards all run U-Boot with a 5 second autoboot timeout. I often want to power-cycle a group of boards, then stop them all at the U-Boot prompt ... [More] before they autoboot. It’s a race to C-x b to all the different buffers in time. I used to frequently miss some buffers; the boards would start booting, and I would have to wait to issue a software reset. It became annoying enough that I decided to create an autostop extension. Luckily, serial-term is written in Emacs Lisp, so I can extend it to do exactly what I want. In this case I want a global “U-Boot autoboot-stop” mode. Here’s what I came up with: First, a variable to to keep track of whether the mode is enabled or not. ;; Detect U-Boot autoboot prompt and stop it. (defvar u-boot-stop-autoboot-mode nil "Non-nil if term-mode should prevent U-Boot from autobooting. Use the function u-boot-toggle-stop-autoboot-mode to toggle.") Then the advice itself. It jacks into the term-emulate-terminal process filter to detect the U-Boot autoboot prompt, then sends a newline in response. (defadvice term-emulate-terminal (before u-boot-maybe-stop-autoboot activate disable) (with-current-buffer (process-buffer proc) (when (string-match "Hit any key to stop autoboot:" str) (message "U-Boot autoboot stopped in buffer %s" (buffer-name (current-buffer))) (term-send-raw-string "\n")))) And finally a function to toggle the advice on and off. (defun u-boot-toggle-stop-autoboot-mode () "Toggle whether or not term-mode should interrupt U-Boot autoboot." (interactive) (if u-boot-stop-autoboot-mode (progn (ad-disable-advice 'term-emulate-terminal 'before 'u-boot-maybe-stop-autoboot) (ad-update 'term-emulate-terminal) (setq u-boot-stop-autoboot-mode nil) (message "U-Boot autoboot will not be interrupted")) (progn (ad-enable-advice 'term-emulate-terminal 'before 'u-boot-maybe-stop-autoboot) (ad-activate 'term-emulate-terminal) (setq u-boot-stop-autoboot-mode t) (message "U-Boot autoboot will be interrupted")))) Now I can enable the mode globally with M-x u-boot-toggle-stop-autoboot-mode and be sure that all the boards will be interrupted in time. It’s worth noting that developing this feature was relatively straightforward. I never left my Emacs session; I developed the code right in ~/.emacs.d/init.el, tested it quickly in a terminal buffer, and confirmed its operation in my existing serial-term buffers. Most of the development time was spent reading the Info documentation for Advice, to figure out how to enable and disable a specific piece of advice. [Less]

This morning I updated the JFreeChart FAQ, in particular the item listing alternative free / open source chart libraries (it's always been there just in case JFreeChart doesn't meet your requirements). There are now 19 projects listed, some of them ... [More] look quite decent. Just now I added the year of the most recent release in square brackets (please let me know if I made any errors in that, the intent was to help identify projects that are still alive): the JZY3D project (BSD) [2013]; the XChart project (Apache 2.0) [2013]; the Project Waterloo (LGPLv3) [2013]; the GRAL project (LGPLv3) [2013]; the JChart2D project (LGPL) [2013]; the JenSoft Java Chart API (GPLv3) [2012]; the JRobin project (LGPL) [2011]; the PtPlot project (UC Berkeley copyright) [2010]; the SurfacePlotter project (LGPL) [2010]; the LiveGraph project (BSD) [2010]; the OpenChart2 project (LGPL) [2009]; the JHeatChart project (LGPL) [2008]; the QN Plot project (BSD) [2007]; the E-Gantt project (Q Public License) [2006]; the Java Chart Construction Kit (LGPL, works with JDK 1.1.8) [2005]; the jCharts project (BSD-style) 2004[]; the ThunderGraph project (LGPL) [2002]; the Chart2D project (LGPL) [2002]; the JOpenChart project (LGPL) [2002]; the MagPlot project (GPL) previously at https://magplot.dev.java.net/; Hopefully you should be able to find something you like in there!

Still being a Swing user, though, I feel often the pain of not having a great looking UI by default.

Instead of writing yet another LookAndFeel from scratch (something that is fun to do, anyway), why not having a Look and Feel based on JavaFX? Here it is:Well, it’s still pretty bare bone… I even don’t have the nice border yet :) Also, the code is really a complicated mess, given I did everything in an half hour of coding, so I won’t release this yet. But maybe I can really make this a Summer project. What do you think? [Less]
