Description

« Hide

Environment: Java 1.5, with cglib-full-2.0.jar in the path.

Calling: new XSteam();

Throws:
java.lang.NoSuchMethodError: net.sf.cglib.proxy.Enhancer.isEnhanced(Ljava/lang/Class;)Z

cglib-full-2.0.jar is in the path for a completely unrelated reason (and not something I can easily change). I'd like to use XStream but don't care about CGLib support.

Joe, can I close this? It is really only happening for the cglib-2.0 version that is more than 3 years old. Since 2.0.1 and later anything works as expected. Since upgrading cglib is quite flawless, I'd like to ignore this as known problem with easy workaround.
