Stuck threads under heavy load #3460

Under heavy load in a production environment we see a dead-lock situation. Here is the thread dump:

AbstractJAXBProvider.getStoredJAXBContext() synchronizes on the static field jaxbContexts and accesses jaxbContexts in line 193. This may cause the problem.

There were also some problems with WeakHahsMap we want to mention:
