The only "documentation" I know of is in the Java launch script itself.
If you look there, with both JDK1.1 and JDK1.2, you'll see that the Java
executable is invoked like this:
exec $DEBUG_PROG "$prog" "$@"
What this means is that if DEBUG_PROG is defined, that program is run
and the name of the Java executable ($prog) is passed as the first
argument. So if you run:
DEBUG_PROG=gdb java -green
it'll run the green-threads java executable under the gdb debugger.
The IBM JDK1.1.8 launch script contains the same thing, so I suspect
this is a general Unix-ism that came from Sun.
