----------------------------------
Oli,
How easy is it for you to reproduce and test this?
I just discovered the call in JAXBContextCache to "remove" was not in a
synchronized block which could definitely cause this. I'm committing that fix
to trunk and the branches, but would definitely like to see this tested to make
sure it really fixes the problem.
