The last tag available is JSR166_PFD [1]. If this is what Sun used for
1.5, then they changed it internally. There are no tags, which are
more recent. Of note, the JAPI reports shows other difference between
Harmony's j.u.c and Sun's JDK 5, so the public API was changed
somewhere. We could just use HEAD if we don't mind starting Java 6
support.
