Question on status of a few bugs in OpenJDK 6

[Krystal Mok]

Hi all,

Guess I'm asking on the wrong list, but I don't know which list I should be
sending this to for OpenJDK 6-only  issues. The jdk6-dev list is mostly
silent now, doesn't seem to be the right place, neither.
Maybe I should be asking the sustaining team?

I was looking at what changes went into recent OpenJDK 6 releases. Turns
out OpenJDK 6 build 23 is the closest version to JDK 6 update 25, and
OpenJDK 6b24 is the closest version to 6u30. Reading through the release
changes [1][2], though, tells that:
1. The loop optimization bug that crashes the VM is fixed:
  7070134: Hotspot crashes with sigsegv from PorterStemmer
2. A few other related bugs aren't included in OpenJDK 6 yet, as of now:
  5091921: Sign flip issues in loop optimizer
  7052494: Eclipse test fails on JDK 7 b142
  7004535: Clone loop predicate during loop unswitch
  7068051: SIGSEGV in PhaseIdealLoop::build_loop_late_post on T5440
  7044738: Loop unroll optimization causes incorrect result
  7077439: Possible reference through NULL in loopPrdicate.cpp:726

I suppose some of these fixes are actually in the product JDK 6u29+
already, like 7044738.

So, questions:
* Could anyone help identify whether these bugs affect OpenJDK 6 or not?
* If they do, what are the plans for porting the fixes back to OpenJDK 6?
* And what is the general plan for future maintence of OpenJDK 6?
* Is there any place in the public that we can track what's going to be
backported into OpenJDK 6?
* Will it sort of EOL along with the product JDK 6?

Thanks,
Kris Mok
