1.8 works fine here.  The Gentoo build had to request the xerces and
xalan tasks for 1.8 explicitly, but otherwise works.  Looks like a
distro packaging issue or Ant bug rather than an OpenJDK or IcedTea
bug.

Fixed.  The build relied on the contents of lib/rt.  What actually
ended up in there depended on the compiler and which classes it
compiled.  In the case of OpenJDK builds, a speedup was added so these
bootstrap classes weren't build as they are already in the bootstrap
JDK.  It now uses rt.jar, which will either be the OpenJDK symlinked
one or the updated version produced by rt.stamp for gcj builds.  A
no-bootstrap --enable-cacao build worked for me with this fix, where
previously it crashed out unable to find java.lang.Object.

Three problems, all on top of each other:

- icedtea-against-icedtea was a pseudo-target rather than a stamp and
so was always being rebuilt.  It's now a stamp.
- Likewise, tools.jar is now tools.stamp.  When tools.jar changed from
a regular file to a symlink, the timestamp of rt.jar was used by make,
which is updated after plugs.stamp is built.  Having to rebuild plugs
causes a domino effect leading to icedtea being rebuilt.
- There was a typo in plugin.stamp so plugin.stamp was never created
but icedtea-plugin.stamp was.

All the above are now fixed and a make jtreg goes straight into building jtreg.
