Description
I was using xstream without any problem unless I created a custom
security manager. When I run my program with security manager
I get the following error in "fromXML()" call.
When I disable security manager everything works fine.
What is the problem?
java.lang.NullPointerException

Hi Suat,
it is normal for any package, that it might need additional rights if running under a SecurityManager. Especially XStream that makes heavy usage of reflection will need additional rights. To get you some idea, I have created a test case:
