That's why we ask JNDI set callByReference... then your client will get a handle to another class loaded in a different classLoader what should be okay.
This exception you're getting is a bug we are fixing early next week.. about classLoading isolations on aspects... if you download sources from the SP branch it should be already fixed... but we don't have a release yet...
this should be out over the weekend/early next week.!
