Comment 1 tvc3 CLA 2011-04-05 04:26:57 EDT 
I am using Eclipse Helios SR2 build ID 20110301-1815. Somehow after a change in the location of a library JAR file from one of my WEB projects/lib folder to a core EAR libraries, the server deployer has since then ceased to work. 

Subsequently, whenever I tried to startup the weblogic server in debug mode, It won't run and always shows Unhandled event loop exception in the error log.

v1.0

The only case that the method will cause ArrayIndexOutOfBoundException is when the extension point load size is 0.  Adding check to prevent the problem to occur.

Fixing the trace information on this new patch to make sure the end loading extension point trace will be produced.
