      The Java generated treeparser doesn't seem to have an initializeASTFactory method.

      Since I'm running initializeASTFactory on the treeparser's own getASTFactory, there isn't much synching being done (by me, anyway). And all it does is set the factory's maximum anyway!

      Hi Harald,

      I was just about to copy your previously posted grammar to see if I
      could reproduce your issues with buildAST. Never mind, seems you've
      fixed it in any case.

      The behaviour you describe (i.e. tree parsers being created with a
      default ASTFactory) is by design. Users are supposed to use the static
      method named initializeASTFactory() - or similar, it's on the
      generated Parsers - to ensure their tree parser's ASTFactory is in
      sync with the Parser's.

      I may be wrong but, I thought this was uniform behaviour across all
      the codegens(?).
