I am using JBoss-3.0.1RC1 on Solaris 2.6 with JDK1.3.1_01. Before moving to this version I was using JBoss-3.0.0 and I got "ClassCircularityError" when accessing my datasource. But then wihle searching the forum and the downloads I found out that the release 3.0.1RC1 has a fix for this problem. In the release notes of the 3.0.1RC1 it is stated that this problem is fixed. But I have to say that it is still there.
I am not doing any stress testing.But eventually I have to do one. I have a simple session bean which talks to the database to retreive some info. But then when I run my client for the first time i get this error on the server. But the client goes through to get the result. Subsequent runs of the client dont throw this error on the server.
One more thing this problem doesn't happen on my Windows NT machine. Same jboss version and same jdk version.
Anybody has any clues on what is wrong.
Here is the server.log
