Description xigua 2007-06-20 23:46:58 UTC 
I was able to manually modified the weblogic9.1 startup script but as soon as the profiler was attached to the JVM, I
started getting a lot of Exception about AspectJ5 can't weave hotswapped class. Our web app uses the load time weaving
feature of aspectj5 and I tried both the 5.1.3 version of the aspectjweaver.jar and the current development version of
the aspectjweaver.jar but neither worked. 

java.lang.Exception: AspectJ5 does not weave hotswapped class (sun/nio/cs/MS1252)

Comment 1 Tomas Hurka 2007-06-21 09:07:23 UTC 
I do not see anything wrong from the profiler point of view. Profiler wants to redefine sun/nio/cs/MS1252 class, which is probably generated on the fly and 
aspectj does not handle it. Note that java.lang.Exception is used to print stack trace only, there is no throw statement. 
ClassPreProcessorAgentAdapter.java source is available here:
