I actually ended up with the similar exclusion list after some 
unsuccessful attempts of backporting.

I was able to backport more  AWT changes from jdk7 and build "non-debug" 
version on VS2003. But "debug" compilation was still broken (due to 
debug ifdefs) and I gave up after some time.

I think this is not possible without toolset update to VS2010, Ivan 
wrote about in February.

I am willing to participate in such compiler update, but two things 
prevents me from doing it:

  - zero windows programming experience
  - no ability to run jtreg test-suite on windows

Some time ago I wanted to set up limited subset of jtreg tests on 6b27. 
I created the subset of ones those run successfully on Linux (in the 
same VM, no shell, takes less then 1 sec each etc.). But I completely 
failed to create the similar "subsubset" for Windows. I tried to run 
jtreg in Windows2000 virtual machine and a lot of 
"successful-and-fast-on-Linux" tests just hang or take minutes to finish.

If you would be able to share the experience of setting up 
pre-integration testing for Windows - it will be really helpful.
