Mukul Gandhi commented on XERCESJ-1538:
---------------------------------------
@ Denis: if you can provide us with a simple java test case, whose
multithreading code base is easy to understand and can unambiguosly demonstrate
that there's something wrong with Xerces's implementation then it would be easy
for us to find an appropriate solution.
the java test case you posted earlier, has huge application domain semantics
that makes harder for us (at least me) to debug the suspected problem. I won't
blame you for that..., since I asked for an end-to-end java scenario with which
you were working -- but unfortunately your application context is overwhelming
atleast for me to focus on debugging.
I hope you may try to post a simplest possible test case, meeting some of the
simplicity criteria listed above so we could quickly focus on debugging aspects.

> URL: https://issues.apache.org/jira/browse/XERCESJ-1538
> Project: Xerces2-J
> Issue Type: Bug
> Components: JAXP (javax.xml.validation)
> Affects Versions: 2.11.0
> Environment: Windows 7 x64, Java 6 Update 26 x64
> Reporter: Denis Orekhov

> I'm using Xerces2 Java 2.11.0 (XML Schema 1.1) (Beta) in my app. Schema
> validation in my app can occurs simultaneously in separate threads.

> test="(count(datapanel) + count(server) =0) or
> (count(*[position()=1 and name()='main_context']) = 1)" />
> </xs:complexType>
> </xs:element>
> And sometimes I have SAXException with text "cvc-assertion.3.13.4.1:
> Assertion evaluation ('(count(datapanel) + count(server) =0) or
> (count(*[position()=1 and name()='main_context']) = 1)') for element 'action'
> with type '#anonymous' did not succeed.".
> I checked my data and schema text before validation error - both is good.
