OpenJDK 8 FreeBSD 10.1 SIGSEGV issues

[Paul]

Hello

This is a thread from FreeBSD Java list.
Issue has been reported to OpenNMS and FreeBSD Java.

It has been advised to send it further upstream to OpenJDK


Nobody seems to want to take ownership of this problem!

Please Help?

Thanks

Another Followup -

hotspot/src/os/bsd/vm/os_bsd.cpp is where mprotect is used and
some of the BSD patches indicate that there might be problem
with the patches.
Has this been looked at as a possible source of the SIGSEGV problems?

---------------------------------------------------------------------------- 



In tracing system calls ....
Multiple SIGSEGV's are occuring
Many are near: system call:
26326: mprotect(0x800659000,4096,PROT_NONE) = 0 (0x0)
26326: SIGNAL 11 (SIGSEGV)
Several others occurred:
26326: 
stat("/usr/local/openjdk8/jre/lib/jaxp.properties",0x7ffffebec078) ERR#2 
'No such file or directory'
26326: SIGNAL 11 (SIGSEGV)
A couple more near:
26326: 
madvise(0x8df4cb000,0xa0000,0x5,0xaaaaaaaaaaaaaaab,0x0,0x80100bbe0) = 0 
(0x0)
26326: SIGNAL 11 (SIGSEGV)

So something in the OpenJDK is having at least a problem with mprotect 
and madvise.
These probably have POSIX and non-POSIX versions on FreeBSD.

So problem is not 1 SIGSEGV but many.

OpenNMS Jira Trouble Ticket

     [http://issues.opennms.org/browse/NMS-7687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40259#comment-40259  ]

Jesse White commented on NMS-7687:
----------------------------------

We would need help from FreeBSD's OpenJDK maintainers to move this forward.

The problem is easy to reproduce, but I haven't had any success in isolating it.
