No. The backports were necessary for applying the security changes and have
been established for a long time in both the proprietary JDK 6 (which the 7
versions are apparently forward-ports from) and in IcedTea.

Not backporting these changes would have meant a complete rewrite of the patches
for a version of AWT that only exists in OpenJDK 6, which seems not only a waste
of time, but also nigh on impossible, given the limited knowledge we have of the
security issues.

Thus, our safest option is to get OpenJDK 6 into the same state as 7, while
remaining compatible.

We'd welcome testing and support on other platforms and, if there are further
backports you require, we'd be happy to consider applying them. We only have
the resources to support OpenJDK 6 on the GNU/Linux platform. If people want
support on other platforms, then they also need to provide the necessary
maintenance.

Please note, however, that we can't discuss security changes until after the
embargo is lifted.
