java launcher option -d32/-d64

[Jesper Wilhelmsson]

Hi,

I think this is a good change. If a flag doesn't make sense anymore we must have 
the guts to remove it. We have way too many command line flags to be sentimental 
about them.

Updating all our tests that use the flag must of course be part of the work done 
to remove the flag. This is something that Kumar needs to take into account and 
staff when planning this work.

Updating scripts and other frameworks that are not part of our shared source 
base can obviously not be part of the work, but will have to be done by the 
maintainers of the scripts and frameworks. This is unfortunate but we can't let 
that stand in the way of a good change. Especially in a major release I think 
this is the kind of changes one have to allow.

One question though, should the flag be deprecated for one release before removing?
