> Client/server messaging uses a Message object containint Parts.  Each Part holds a HeapDataOutputStream that serializes the item placed in that Part.  Once the Message finishes transmitting its contents it clears the "parts" array, setting it to null, but this array may consume a sizeable amount of heap - mainly in the byte-buffer "chunks" list held in the HeapDataOutputStreams.  It would help with GC if these "chunks" lists were cleared as part of Message clean-up.
