RFR [7] 8133206: "java.lang.OutOfMemoryError: unable to create new native thread" caused by upgrade to zlib 1.2.8

[Nikolay Gorshkov]

Hello,

I'd like to ask again for integration approval for the following fix
in core-libs area:
- Bug report:
  https://bugs.openjdk.java.net/browse/JDK-8133206
- Webrev of the fix:
  http://cr.openjdk.java.net/~nikgor/8133206/jdk7u-dev/webrev.01/
I just confirmed that this fix applies cleanly to the current jdk7u-dev/jdk
repository, and the produced FVB passes the unit tests provided by Alex
Kashchenko.

We have already tried to get approval for this fix almost 11 months ago,
but without much success.
- JDK 7u review request:
http://mail.openjdk.java.net/pipermail/core-libs-dev/2015-October/035884.html
- JDK 9 review request:
http://mail.openjdk.java.net/pipermail/core-libs-dev/2015-November/036463.html
There was a valid concern that the actual root cause may be in third-party
software. But anyway, we are not in a position to modify it. From other side,
there are customers that need the problem be fixed and currently use custom
builds. So we are still interested in delivering this fix at least to
jdk7u-dev.

Thanks,
Nikolay
