Hi,

Today I wanted update my small Apache Struts 2 project to the latest version but after re-deploying the app I have got the below error, no idea what's wrong :\ The listener just nulls the SecurityManager: OgnlRuntime.setSecurityManager(null); Locally everything works just fine. 

SDK version: 1.9.38
Apache Struts: 2.5.2

Looks like the problem is here with Class.forName("javassist.ClassPool"); - whether access to Class.forName() has been blocked?

Yup, AppEngine doesn't accept javassist - is that documented somewhere or just a bug?

The problem is inside Javassist, switching from version 3.20.0-GA to 3.18.2-GA solves the problem
