Hi all folks,

I try to play with tracing and additional dynamic Instrumentation (based on Websphere 7.0 and Introscope Agent 9.5.2) and got something like this

 

[27.05.15 18:29:14:785 CEST] 00000022 LocalExceptio E   CNTR0020E: EJB threw an unexpected (non-declared) exception during invocation of method "onMessage" on bean "BeanId(rops#PCEServer.jar#PCEJmsReceiver, null)". Exception data: java.lang.IncompatibleClassChangeError

a short time later, the Application seems to work, but the exception was written in the log many times a minute.

My problem is, all Applications are running on the System (AIX Lpar) start to write this exception, not the traced/instrumented Application only.

 

Any idea what's going wrong,

Lutz
