OpenJDK6 B31 Now Available

[Yuri Gaevsky]

Hello.

The OpenJDK6-b31 build should succeed without the recent AWT-related
changesets:

It looks like the importing of several changesets from 7u (marked with [*]
above) was unintentional. Backporting of D3D pipeline [1] and other
associated changes into OpenJDK 6 requires much more work due to switch to
modern DirectX and/or MS VC compiler. Some time ago there was a discussion [2]
regarding the upgrade to MS Visual Studio 2010. Now with Windows XP retired we
would ultimately switch, and as before we are ready to participate in that.

Please let us know if you need any help with pre-integration testing for
Windows to prevent similar unexpected build failures in future.

Thanks,

Andrew Hughes might be in a better position to answer what happened in
this case.

In general, the security patches are taken from 7u and sometimes don't
apply to 6 as is. So we backport additional patches until the security
patches apply. The Windows patches don't get any special treatment; we
just backport whatever is needed until the security patches apply
properly.

In the interest of longer-term maintenance, I think it's better to get
closer to 7 rather than further away from it. I would strongly recommend
backporting additional changes from jdk7 to jdk6. If you can point me to
the patches, I can include them in jdk6.

Thanks,
Omair
