flex blazeds spring exception translator

Question

I am using spring exception translator to wrap java exception into flex exception. eg

 public void testException()throws Exception{
       throw new Exception("my exception");
}

But for some reason, I am getting IllegalAccessError. The code sections are entering the testException and the Translator class.

Question: why it trying to get log target level ? Can someone help me resolve this please.

Below is the lines from the log:

MyExceptionTranslatorImpl.translate()class java.lang.IllegalAccessError

MyExceptionTranslatorImpl.translate()java.lang.IllegalAccessError: tried to access method flex.messaging.log.Log.getTargetLevel()S from class flex.messaging.MessageException

MyExceptionTranslatorImpl.translate()tried to access method flex.messaging.log.Log.getTargetLevel()S from class flex.messaging.MessageException [BlazeDS] tried to access method flex.messaging.log.Log.getTargetLevel()S from class flex.messaging.MessageException

This turned out to be mismatch in jars. Thank you Cornel Creanga for the initial response. I also verified that throwing an java.lang.exception was enough to catch the error on the client side.
