Remarks
Produces a constant method handle of the requested return type which returns the default value for that type every time it is invoked. The resulting constant method handle will have no side effects.
The returned method handle is equivalent to empty(methodType(type)). It is also equivalent to explicitCastArguments(constant(Object.class, null), methodType(type)), since explicitCastArguments converts null to default values.
