It allows using NonNMethod code space for method handle intrinsics which are needed urgently if the other code cache spaces are full. There are other options (see JBS issue), but this one appears to be the simplest one.

It sounds like using nmethods for compiled method handle intrinsics isn't necessary and causes problems.  What if we store them as MethodHandlesAdapterBlobs like we do for the interpreter?  Lookup would need to go through method->adapter() instead of method->code().  Is there already an RFE filed for this?
