I think you're missing one of the main points here... he did NOT say
that they would not compile at all -- he said they would not compile on
the current Gentoo ebuild base (e.g., "... using a 1.5 JDK to emerge
your system").

Then, did you see the rest of his message, the part talking about the
1.5 overlay that is being worked on?  The main point of the overlay is
to get these "incompatibilities" resolved.  Then the "fixed" ebuilds
from the overlay can become mainstream in Portage.

This stuff takes time, especially when system-level stability issues
stand in the balance.
