Believe me, I understand that.  But when this app (and we're talking 
literally in excess of a million lines of java code) was first written in the 
late '90s, a lot of essential stuff (e.g. SSL/certificate related) wasn't 
available anywhere except in these packages.  So the choice was to either not 
have a feature - or to use a package that might not be supported in some 
distant future.

Anyway, it's not a great inconvenience to switch manually to Java 7, after 
compiling in Java 6.  I was just hoping for more flexibility.  It would seem 
to me, at least from a GUI perspective, moving the platform combo box from 
the top-level into each one of the tabs (compile, run, etc.) would do the 
trickā€¦.but that suggestion could be part of the RFE bug I'll write.

Thanks again for trying to help.
