[OpenJDK 2D-Dev] RFR(XS): 8042090: Fix invalid variable names in sun/java2d/loops/ProcessPath.c

[Phil Race]

I don't see any harm in this change but I also don't see any warnings 
about this
in the RE build log files  for Solaris or Linux .. please push to 
9/client (I note your
change set is against 9/dev). Also label the bug 'noreg-cleanup' else SQE
will be asking for a regression test ...

thanks,

-phil.
