OpenJDK Build Issue -- SIGSEGV at OperatingSystemMXBean
getTotalPhysicalMemorySize

I¹m looking for some guidance on configuring OpenJDK correctly for some
platform.
We recently noticed a problem where connecting to a java application
(running using OpenJDK 6-b20_4) on a remote machine (running FreeBSD 7.2)
using JConsole kills the remote application. The remote JVM crashes due to
a segmentation fault almost immediately after a JConsole instance connects
to it.
I traced the problem to the getTotalPhysicalMemorySize() function in the
OperatingSystemMXBean. I can reproduce the segmentation fault using the
unit test for this method that comes with OpenJDK (
jdk6/jdk/.../test/com/sun/management/OperatingSystemMXBean/GetTotalPhysicalM
emorySize.java).
This problem seems limited to OpenJDK. The same unit test, compiled and
executed using an older Diablo build (1.6.0_07-b02), runs without error.
Direct calls to the sysctl method (see libc, sys/sysctl.h) are successful,
as are calls to the sysctl utility (e.g. sysctl hw.physmem). We were able to
reproduce this issue on different machines, using Jconsole executables from
OpenJDK & SUN JVM distros (v6).
Does anyone have any suggestions as to build settings or any other
configuration items we should look at to resolve this problem?
Regards,

BTW, I included the segmentation fault details generated by the
GetTotalPhysicalMemorySize unit test
