Hi,
I've been trying to track down memory leaks in our application and have
noticed that the XMLGrammarLoader internally retains hard references to
schema grammars after completing a parse. This occurs in the grammar
bucket and XSDHandler also keeps an import map, there may be other
places too. It does remove them on the next parse, but this kind of
thing tends to obscure real leaks. Discarding the parser is an option
but it isn't ideal as it seems to involve quite a performance overhead
compared with reusing the same parser.
I've also found that XSDHandler also has a field 'fParent' which appears
to be a stack of XSObject's. This is never cleared, only grown as
required, which means that an object that finds its way into here may
well never be garbage collected.
Thanks,
Chris Simmons.
