[8u] RFR 6424123: JVM crashes on failed 'strdup' call

[Zhengyu Gu]

Hi,

I would like to backport this patch to 8u for the parity of Oracle 8u271.

The original patch does not apply cleanly, as 8u code diverged from jdk9.


Original bug: https://bugs.openjdk.java.net/browse/JDK-6424123
Original patch: 
http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/5217fa82f1a4


8u webrev: http://cr.openjdk.java.net/~zgu/JDK-6424123-8u/webrev.00/

Test:
   tier1 on Linux 86_64

Thanks,

-Zhengyu
