Trying to get straight to the VM constant pool without going through the layers of universe lookups. The VM constant pool resolves a method without resolving its return/parameter/locals types, whereas the universe is usually eagerly tries to resolve return/parameter/locals. Thus, this method can be used when the JavaMethod is needed even when the universe resolution fails. Since there might be multiple constant pools that wrap each other for various stages in compilation, potentially each with a different universe, we go down until the constant pool found is not a WrappedConstantPool.
