I am running Jboss 3.0 with Tomcat 4.0 and Oracle 9i. I am getting a ClassCircularityError when I hit my database connection pool for the first time. Everything executes fine but I still get the error. What does this mean? I have attached the full error above in a .txt document.
This is caused by a bug in the JDK. It is reportedly fixed in JDK1.4.1. As an alternative, JBoss 3.0.3 contains a work around.
