---------------------------------
> GrammarResolver never clears internal cache of Grammar instances

>
> Key: XERCESC-1216
> URL: https://issues.apache.org/jira/browse/XERCESC-1216
> Project: Xerces-C++
> Issue Type: Bug
> Components: Validating Parser (XML Schema)
> Affects Versions: 2.4.0
> Environment: All platforms
> Reporter: David Bertoni
> Assignee: Neil Graham
> Priority: Blocker
> Fix For: 2.5.0
>
>
> I may be misunderstanding how this should work, but
> GrammarResolver::resetCachedGrammar() clears the associated XMLGrammarPool
> instance, but does not clears its own cache of pooled grammars, stored in the
> member variable fGrammarFromPool. The result is a dangling pointer to a
> Grammar instance that no longer exists. I've applied the following patch to
> my local copy of Xerces-C, which seems to clear up the problem.
> cvs diff GrammarResolver.cpp (in directory
> V:\xml-xerces\c\src\xercesc\validators\common\)
> Index: GrammarResolver.cpp
