In CVS
erm, forgot that it dropped ~x86-bsd keyword because unkeyworded deps dev-java/asm-3.0 and dev-java/backport-util-concurrent-3.0 so bsd please keyword that and pmd-3.9 back. Note that backport-util-concurrent needs java5 flag to pull the only available jdk on bsd. But you probably handled this before with another package and have java5 use.forced?
All rekeyworded; the java5 useflag is forced enabled on all packages for Gentoo/FreeBSD.
