There are changes in the official 6uXX releases which don't get
backported to the corresponding OpenJDK hsx repositories. These are
mainly security fixes but I also recall another example which was
related to compressed strings (see

As you probaly now, the official JDK6 update releases contain HSX
version with incremented sub-numbers (HS20.1bxx, HS20.2bxx). They are
all different from the HSX repository in the OpenJDK which usually
remain at a certain build number and dont increment the sub-number. I
would definitely prefer to have one "golden" HSX repositotry in the
OpenJDK which contains ALL the changes of the corresponding HSX
versions from the closed JDK (maybe with a certain delay for security
fixes which would be no problem).
