openjdk problem with OpenNMS

[Paul]

Followup -

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.
