[ http://issues.apache.org/jira/browse/XERCESJ-1080?page=all ]
Michael Glavassevich resolved XERCESJ-1080:
-------------------------------------------
Resolution: Fixed
Thanks for reporting. Should be fixed in CVS now.
> XSAttributeUseImpl.getConstraintValue() might cause NPE
> -------------------------------------------------------
>
> Key: XERCESJ-1080
> URL: http://issues.apache.org/jira/browse/XERCESJ-1080
> Project: Xerces2-J
> Type: Bug
> Versions: 2.6.2
> Environment: Xerces2-J CVS HEAD (May 12, 2005)
> Reporter: Kurt Riede
> Priority: Minor
> Attachments: attP006.xsd
>
> In case of error "a-props-correct.2" (Invalid value constraint value '%1' in attribute '%2'.), attribute fDefault or fDefault.actualValue might be null and the code might result in a NPE.
> How to reproduce: Example from xml schema test suite:
> msxsdtest\attribute\attP006.xsd
> In my case, when anlysing invalid schema files (as good as possible), it is important not to have this exception, so I'm working with my own patched version of Xerces2-J. It would be nice if you would fix this somewhen.
> My fix is quite simple: just check on null:
> Old:
> return getConstraintType() == XSConstants.VC_NONE ?
> null :
> fDefault.actualValue.toString();
> New:
> return getConstraintType() == XSConstants.VC_NONE ? null :
> (fDefault == null ? null :
> (fDefault.actualValue == null ? null :
> (fDefault.actualValue.toString())));
