Honestly, I have no idea what could possibly be causing this. That line in the code (assuming recent version of CXF) is just:
BusHolder h = threadBus.get(); so the only possible way to get an NPE there is if threadBus is null. However, that variable is set via the static initializer: protected static ThreadLocal<BusHolder> threadBus = new ThreadLocal<BusHolder>(); and not ever set anyplace else. Thus, there should be no way for that to be null. I DID just change it to be a ??final?? variable since it should only be set once and never set again. That should allow the jit to optimize the access better since it doesn??t have to check any of the address lines and such from core to core, but that still shouldn??t have any impact on this.
