They are occasional but a build of openjdk-7 bootstrapping from itself
is very likely to end up with a locked up javac process. I've just set
such a build going with the openjdk-7 build-dependencies and some extra
debug packages installed in the build chroot to see if I can get a
useful backtrace. Will be tomorrow morning when I look as I am now
heading off for the night.
Cheers
Michael.
