RFR(XXS): 8156226: DiagnosticCommandImpl::invoke throws NoSuchMethodException even if the method actually exists but parameters are wrong

[Alexander Kulyakhtin]

Hi Kirill,

(I'm not a reviewer)

Is there a specification of what shall be thrown, or the justification of the changes done?
One can think that the currently thrown NoSuchMethodException is correct since　methods, which differ in signature only, are still different methods. 

Best regards,
Alexander

Dear all,

Could you please review this small fix for 8156226?

A case when a method exists but parameters' signature is wrong now 
causes new ReflectionException(new IllegalArgumentException()) thrown 
instead of new ReflectionException(new NoSuchMethodException()).

Thank you.
