[7u-dev] Request for Approval and Review: 6883953: java -client -XX:ValueMapInitialSize=0 crashes

[Vladimir Kempik]

Hello!

I'd like to ask an approval to backport 6883953 into 7u-dev.

The patch does not apply cleanly, the required modifications are
quite small.
I will need a review for this.

The webrev for jdk7: http://cr.openjdk.java.net/~vkempik/6883953/webrev.00/

The difference, compared to jdk9 is the code around the added lines.

Bug: https://bugs.openjdk.java.net/browse/JDK-6883953
Jdk9 changeset: http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/b97166f236bd
Jdk9 review: http://mail.openjdk.java.net/pipermail/hotspot-runtime-dev/2014-May/011630.html
http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2014-May/014527.html

JDK8 change is on the way as well.

The change was tested with jprt on all supported platforms.

Thanks, Vladimir.
