o Added FailureTest1 to test data consistency on simulated process crashes o Removed old c++ internal hashmap o Implemented a cachedEntrySet in PSLM o Added private AnyPersistent shell subclass to use interally as lock in transactions; includes package static asLock o Moved PersistentConcurrentHashMapInternal to lib.util.persistent.package o HashMapInternal uses above asLock() method to get Transaction compatible object for locking o Eliminated use of phantom references for coupling PersistentObjects to garbage collection and reduce heap footprint o Corrected most method visibility issues in AnyPersistent o Fixed equatesWith in PersistentString o Fixed deadlock pattern in ObjectCache.objectForAddress

o Using direct JVM reads for all MemoryRegion reads and using direct JVM writes for Flushable and Raw MemoryRegions. o MemoryRegions are now parameterized with their kind (Raw, Flushable, or Transactional). o Parameterized allocation/reallocation/fromAddress for Heap o added copyMemory/setMemory to Heap

o Improved hashing algorithm of internal hashmap o Added PersistentUUID class o PersistentString now implements EquatesWith o Inner transaction objects are elided o Transaction object-to-lock arrays are eliminated o Cached PersistentObject type o Refactored Transaction/XTransaction
