Description

the MetaClassRegistry is using a subclass of WeakHashMap to store mapping between classes ClassLoader and MetaClass. The WeakHashMap is not threadsafe and my cause strange side effects in a multi threaded environment. such effects are possibly loosing of set MetaClasses and overwriting freshly generated MetaClasses. the same for Classloader is possible.
