they differ between 1.3 and 1.4, I know the launcher launches the desired
version). The information required to use a JRE is the whole directory
she-bang for a JRE, so I'd be really surprised if its not run in a separate
thread by Eclipse....
It would be hard to make a 1.4 compatible build using a 1.3 compiler, since
1.4 didn't necessarily exist "back then."
Can someone working on the compiler interface answer this question?
Thanks and have fun! - Bob

Oh Eclipse itself will certainly run in whatever JRE you tell it to,
and will also launch your application for run/debug in whatever JRE you
tell it to (separate decision). That doesn't mean it uses the JDK's
compiler, which I believe is what the OP was asking.

The compiler uses the JRE's library to compile against, but it doesn't
use a JDK's compiler - so you could actually use Eclipse without having
a JDK installed, as far as I know.

We don't use javac. We use the Eclipse compiler inside an ant javac
task.
