It's worth a try, but they've been pretty unhelpful in the past. The
OpenJDK6 toolset is a mess (being some fairly random point in the
development of the 7 compiler) and their main contribution has being
to break the TCK run.
Perhaps, but we really need their input for anything non-trivial on
the compiler. The type inference logic is very convoluted, and it is
extremely difficult for anyone to look at a patch that fixes one thing
and know that it doesn't break something else. It's really easy for a
fix to "work" for, say, building JBoss but not Eclipse.
It's arguable whether a patch for something that has been wrong for
the whole life of OpenJDK 6 should go in now.
On that note, a good initial test for this would be to see if the
version passes the TCK. Then post to compiler-dev and jdk6-dev.
Right. That's the right way to start.
