Sorta kidding -- see the ;-) ?

But isn't Red Hat kindgly giving time of some employees to work on IcedTea, and didn't they do the same for GCJ ?

Very reassuring. So it's only the work involved in checking each one of thousands specs.

I remember being bitten by this issue on OpenJDK 6 x Java 5. I even submitted a patch to Fedora Xerces package, so I could run Fedora provided ant with proprietary Sun JDK 5. Nice being able to say I had a small contribution for the wonderful distro which is Fedora. :-)

Thanks for the info.

So all F16 packages build with OpenJDK 6 are supposed to work with the also supplied GCJ ? Or didn't you tested so far ?
