Hi all,
can anybody please review two quite simple changes in JVM initialization
code? Webrev is available at:
http://cr.openjdk.java.net/~ptisnovs/StackShadowPagesCheck/
When -XX:StackShadowPages is set to negative integer or zero value, JVM
segfaulted on Linux and, according to
http://bugs.sun.com/view_bug.do?bug_id=6885308, hangs up on Solaris
(although I only check this issue on Linux)
I also would like to add more check for -XX:StackRedPages,
-XX:StackShadowPages and -XX:StackYellowPages options to avoid issue
described in the bug report mentioned above
(http://bugs.sun.com/view_bug.do?bug_id=6885308) but I'm unable to find
relevant information about proper conditions (it may depends on page
sizes, VM stack size etc.). Any ideas?
Cheers
Pavel Tisnovsky
