Subject: [PATCH]  Fixed the Reference of the metaclass in ClassInfo.java to
 use a WeakReference now, so the Reference is cleaned up nearly immediately
 after freeing the last strong reference of the metaclass.

Prior it was used a SoftReference which prevents the ClassLoader, the ClassInfo and the Metaclass instances from beeing garbage-collected
until the JVM runs nearly into an OutOfMemoryException (PermGen). This leads to a JVM which is always near the maximum of memory usage.
