You are probably right regarding the future versions of the Solaris 
Studio compiler. Here is a new webrev with the check being >= 513 (which 
is indeed 12.4).


I still only apply it to adlc as that's where +w is active. I doubt +w 
will be activated for the rest of hotspot anytime soon as the amount of 
warnings triggered is quite substantial.

The warning is only activated by +w, which is turned on for adlc but not for the rest of the hotspot build. Based on this, I have revised my proposal to just disabling this warning for adlc and the particular compiler version.
