Changed LibraryVMInterfaceImpl.getWrapperFromClass() and getWrapperFromClassLoader() from using reflection to a map.xml implementation to improve performance.
It turns out that Constructor.newInstance() calls Class.getModifiers() which indirectly uses getWrapperFromClass() and using reflection significantly affected deserialization performance.
