Did you use the same JVM version? Mabe it is an issue what the JVM provide or how it is implemented.
Not sure but IIRC JAXB was first a separate jar and then integrated ...
Yes JVM version is same on both machines.
Issue is resolved.
Issue was - Source server was in running state when we copied to Target server.
We have stopped the source jboss server and again copied then it started working.
But still not clear what difference does it make when we copy entire jboss in running state ? After copy we also deleted log, tmp, work, data folder then also it was not working.
Other than these folder, internally does it cache anything anywhere?
IIRC delete the directories should be enough.
Maybe you compare the directories (ecept tmp data work) for both copies
