This is a pretty weird error. I've never encountered it before, but judging by a few topics on SO like -
https://stackoverflow.com/questions/30812293/com-thoughtworks-xstream-security-forbiddenclassexception
it is most probably something related to the permission settings introduced in recent XStream update.

So a few things to pinpoint the problem:

• Which WebLaF version are you using?
• Which XStream version are you using? (maybe you have a newer version than WebLaF uses)
• Which Java version are you running the code on?

Also, as a possible temporary/quick fix - does this solve the issue for you?

XmlUtils.getXStream ().addPermission ( AnyTypePermission.ANY );

I already have this added in latest snapshot versions, but I'm pretty sure it was missing in previous release version.
