[RFC][icedtea6]: RH706066

[Denis Lila]

Hi.

This bug will require a couple of backports:
http://hg.openjdk.java.net/jdk7/jdk7/langtools/rev/36c4ec4525b4
http://hg.openjdk.java.net/jdk7/jdk7/langtools/rev/dc550520ed6f

The attached patch does this. It doesn't contain the regression
tests T6369605a.java and T6369605b.java because even after the
patch was applied these tests were failing.

I think this is ok though because they fail with ecj and
proprietary javac too. What's probably happening is that
they're assuming other changes in the compiler in addition
to the fix for 6369605.

I've attached three tests I wrote that were derived from
commons-discovery (whose compilation fails, as detailed
in the bug report). All three compile with ecj and proprietary
javac, but they fail with openjdk javac before this backport.
With the backport they compile.

I haven't tried compiling commons-discovery yet. I will
do that soon and give an update.

I ran the langtools regression tests, and there were no changes
in the results.


ChangeLog:

2011-06-01  Denis Lila <dlila at redhat.com>

	* Makefile.am: Apply patches.
	* NEWS: Update with backports.
	* patches/openjdk/6938454-generic-type.patch:
	* patches/openjdk/6369605-unconstrained-type-vars.patch:
	New patches. Compiler backports.

Is this good to go (contingent on commons-discovery compiling
successfully)?
The bug was reported against F14, so this should go into 1.9,
1.10 and head. I would like to let it soak in head for a week
or two before I push to 1.9 and 1.10 though.

Regards,
Denis.
