Odd behavior in WAS 7.0: java.lang.ClassNotFoundException: class java.lang.NullPointerException: null

Question

I\'m working with WAS 7.0 and I found this error:

[27/10/13 11:55:06:727 CET] 00000023 servlet       E com.ibm.ws.webcontainer.servlet.ServletWrapper run [Servle         


        

Answer 1

I found the problem. Despite what it looks like, it is not a platform problem, I just forgot to initialize an ArrayList and hell broke loose. Hooray for such useful compiler '¬¬

Answer 2

The version of Java 6 included in WebSphere Application Server has the lost the fix for Java bug 4256569, which obscures the actual cause of the failure. If this issue is important to you, I recommend opening a PMR with IBM. I verified that this issue has been resolved in the Java 7 included in WebSphere Application Server 8 and later.
