Eirik Bjorsnos commented on CXF-4751:
-------------------------------------
Jason,
Yes, you can exchange "Java 6" in my last comment with "stock Java6".
The work-around of adding Xerces 2.7.1 or newer to a Java6 classpath should be
documented.
> Schema validation causes false validation error under concurrent load for on

> Key: CXF-4751
> URL: https://issues.apache.org/jira/browse/CXF-4751
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.6.1, 2.7.1, 2.7.2
> Environment: Java 6

>
> We're observing a small, but noticeable number of requests in our load tests
> failing with MarshallingErrors caused by schema validation failing when
> marshalling a JAX-WS annotated response object.
> The service is a JAX-WS endpoint with Message.SCHEMA_VALIDATION_ENABLED set
> to SchemaValidation.SchemaValidationType.OUT (or BOTH).
> The error is reproduced in a small JUnit test case. The error could not be
> reproduced with requests run on a single thread. On two or more threads, the
> unexpected result is consistently reproducible.
> Here is a typical stack trace:
