Glen Mazza commented on CXF-4411:
---------------------------------
I'm not sure if wsdl2java is expected to be thread-safe, or even if it can be,
especially in cases where the same output files are being generated from the
same WSDL in multiple places. Are you (A) generating from the same WSDL into
the same output folders from multiple POMs, or are you (B) calling wsdl2java in
multiple places with different WSDLs & different output folders, or are you (C)
simply just calling wsdl2java once but the splitting up of it into multiple
threads is what's causing the concurrent modification exception?

> Key: CXF-4411
> URL: https://issues.apache.org/jira/browse/CXF-4411
> Project: CXF
> Issue Type: Bug

> We're getting a concurrent modification exception while running a parallel
> build (-T C5) using Maven 3. Reproducability is low, so it seems to be some
