dev-java/icu4j-4.0.1 was released on 2009-01-15.
dev-java/icu4j-4.2 was released on 2009-05-08.
4.0.1 bumped. Just reused the 4.0 manifest, hope it doesn't break osgi stuff, if it does, your fault :) 4.2 will be another slot.
OK bumped in new slot. OSGi dropped because I haven't seen a osgi manifest for 4.2 yet. Tests restricted, one failed for me due to not finishing in 10 seconds, stupid.
