Hi Kumar,

what do you intend the outcome to be if someone specifies -d32 or -d64,
respectively? Simply ignore it, print a warning - or fail?

I know a number of scripts and tools which use -d64 for backwards
compatibility with JDK 7, so if it's not too much trouble to keep at
least the -d64 flag until 10, i.e., simply accept the option and do
nothing, I for one would have less things to worry about.
