JavacProcessingEnvironment is releasing the Name table even if it's supposed to be shared. Here is a time stack traces I get when compiling.
(The lines in the trace might be a bit off, since I have local changes.)
Do processing causes close() on the compiler which in turn calls names.dispose();
The line after compiler.close() is currentContext = contextForNextRound(currentContext, true); It creates a new context trying to share the names (the last param is true.) Unfortunately the name table was already disposed.
