I agree with you wholeheartedly if we were talking about the LGPL.
But with the GPL it's more dicey. If at any point in the process the
two components share address space, names, or the like then it's
possible that the resulting executable is deriviative thus subjecting
the proprietary jar.

You need to ask the author of the GPL jar about the intent of use.

Frankly this discussion gets really old. I just don't see why
proprietary developers can't understand the underlaying intent.
When someone slaps a GPL license on some code: THEY DON'T WANT YOU
TO USE THAT CODE WITH PROPRIETARY CLOSED SOURCE! Because if they
did there are a zillion other licenses that they could have used
instead, like the LGPL, BSD, ZPL, Artistic, or wxWindows library
licenses for example. GPL markes the code for use in Open Source
only projects.

The answer to the nieve question "Can I combine my proprietary
closed source to GPL code?" should be a flat NO!

I just wish folks would stop string to put that square peg in the
round hole. In the end it doesn't fit.
