Ok, are these backports from OpenJDK7? I haven't seen anything on the
list other than the commits.

Same bug, same bug ID, different patch.  The two tests affected in
hs17 aren't present in hs14, but a test that's not in hs17 is.

What tests?  JTreg or something else?

I think IcedTea6 has support for building against hg.  We should do
that before the release.

When b17 is released, can we have a summary page like that published
for the OpenJDK drops:
http://download.java.net/jdk7/changes/jdk7-b72.html ?
These make it much easier to work out what's changed when problems
occur.  Xiomara produces these AFAIK.

Ok, well part 1 of the Nimbus patch is there for review when you're ready :)

hs16? :)  We have a stable tree for that now.

There is a HashMap performance improvement that's in OpenJDK7 (and I
believe the JDK6 proprietary builds) that should be backported.

If Gary's Zero patch is approved for 7 during its lifecycle, we should
backport this to 6.

Plus as many existing IcedTea bugfixes as we can get through the
review process I guess...
