This method was added prior to `MethodTypeDesc`.    MethodTypeDesc::ofDescriptor` and `MethodTypeDesc::resolveConstantDesc` would be the alternative way to get back the method type.  I tend to think that `descriptorString` would not need that distinct class loader note (as it would use the Lookup class to resolve instead).
