Chris Simmons updated XERCESJ-1563:
-----------------------------------
Attachment: xerces-grammar-pool.txt
Patch with a test and fix for the issue. The fix is simply to initialize the
schema description before calling into the grammar pool which is what used to
happen.
> XMLGrammarPool receives uninitialized XMLSchemaDescription
> ----------------------------------------------------------
>
> Key: XERCESJ-1563
> URL: https://issues.apache.org/jira/browse/XERCESJ-1563
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema API, XNI
> Affects Versions: 2.11.0
> Environment: Linux
> Reporter: Chris Simmons
> Labels: patch, test
> Attachments: xerces-grammar-pool.txt
>
>
> When the schema validator requests a grammar from its grammar pool it
> initially passes an XMLSchemaDescription in which only the namespace is set.
> Moreover, the description it not reset at this point so it may have fields
> set based on some previous unrelated grammar.
> This is a regression since 2.9.1.
> Our grammar pool uses the same logic as our entity resolver to figure out
> where a grammar came from. This relies on the same information being
> available when retrieving a cached grammar and parsing it for the first time
> (particularly the context type, schema location hints and base system id).
