Hi Sunny,
as per the current 7u60 putback process [1], these three bugs need to
have the '7u60-critical-request' label added to the master bug record.
I've just done that now. Once they're marked approved, let's revisit
this thread.
Since the fixes are in the hotspot area, the backports should be pushed
to the hotspot team integration forest. alejandro.muri...@oracle.com can
help you with that nearer push time.
regards,
Sean.

Hi all,
This is a request to backport a jdk8 fix into jdk7u60, along with subsequent
changes to the regression tests:
8017498 : JVM crashes when native code calls sigaction(sig) where sig>=0x20
https://bugs.openjdk.java.net/browse/JDK-8017498
The current jsig implementation is unable to deal with sigaction request if signumber
is > 32. The patch modifies the signal handler so that signal > 32, which is
not used in the JVM, to ignore and install the handler request directly.
This fix is already included in jdk8's hotspot as:
http://hg.openjdk.java.net/hsx/hotspot-rt/hotspot/rev/732af649bc3a
The discussion thread for Java 8 can be found here:

Notice that current the regression tests that Calvin has provided has a few
issues and this has been fixed in the following subsequent updates:
Bug fix 1 (native code failed to compile on some platform, 8020791):
http://hg.openjdk.java.net/jdk8/jdk8/hotspot/rev/72727c4b6dec
http://mail.openjdk.java.net/pipermail/hotspot-runtime-dev/2013-July/008312.html
Bug fix 2 (failed to find gcc, 8021296):
http://hg.openjdk.java.net/jdk8/jdk8/hotspot/rev/f9ee986a9fea
http://mail.openjdk.java.net/pipermail/hotspot-runtime-dev/2013-July/008421.html
I have verified that if you applied the original bug fix and then subsequent
testbug fix to the JDK 7 branch, it applies cleanly and resolved the issues.
Thanks.
