Old version of cglib 2.0 creates problems with Java 2 security in WebSphere 5.1

From a customer:

Confluence includes an old version of cglib-2.0.jar, that does not appear to be the final version, possibly a release candidate version. Upgrading to cglib-full-2.0.2.jar should fix the problem:
http://www.ibiblio.org/maven/cglib/jars/cglib-full-2.0.2.jar

The final version of cglib-2.0 makes "generated classes have the same protection domain as cglib.jar (have the same signer and code base). It can be useful if hibernate is used in app server with security manager or for Web Start applications."

With the old version of cglib, you will get the following error in WebSphere 5.1, even with full permissions in your policy file:
