> Apply to this patch, 
> If proxy target class is interface, generated proxy class name changes 
> form "org.javassist.tmp.java.lang.Object_$$_javassist_0"
> to "org.javassist.tmp.java.util.List_$$_javassist_0".
> All interface generated proxy class name is "org.javassist.tmp.java.lang.Object_$$_javassist_(number)"
> Because proxy class name pattern is monotone,
> duplicate proxy class name, then it causes LinkageError.
