Hi Shilpi,

In principle this change is ok, however these methods are kind of special 
because they are called by code generated from LambdaForms with erased types.

IIUC the casts can serve as belts-and-braces checks just in case that generated 
code passes something that is not of the correct type. By removing the casts 
it’s possible to erroneously pass in something of another type that the runtime 
treats erroneously as if a MethodHandle or MethodType, and then strange things 
happen. The casts will ordinary be removed by the runtime compiler. By removing 
them from the Java code it might slightly improve C2 compilation time.

Approval from Vladimir/John would be good.

Paul.
