Fwd: Re: [opennms-devel] OpenNMS 1.14+ on FreeBSD 8, 9, 10, 11

Forwarding to the java on freebsd project......

Hi Java!

We have issues here that are problems with openjdk 7 and 8.

Please acknowledge and confirm so we can all work on this together and 
get this resolved asap.  I would like to see OpenNMS in the ports tree 
soon and this has already gone on for more than 6 months.

Thank you!

P.

If the develop branch already exists, then

# git checkout develop

You should also pull up the latest commits.

# git pull

Then you could do the git merge.


When I run OpenNMS 16.0.0-SNAPSHOT (develop) with either OpenJDK7 or OpenJDK8, I get a JVM crash dump.

When I had installed OpenJDK7 and 8, I noticed there were config options for debugging. For both the slowdebug and fastdebug options, I re-installed OpenJDK8 and ran OpenNMS. Both times the JVM crashed within minutes of startup.

Is there a way to compile OpenJDK8 using GCC rather than clang?

Is there a way to compile OpenJDK8u60-b09 within the FreeBSD ports framework and use that to test running OpenNMS under?


I found this PDF from Oracle on troubleshooting guide for Java SE 6, and assume it also applies to OpenJDK.

http://www.oracle.com/technetwork/java/javase/tsg-vm-149989.pdf

There were two JVM arguments that I found that are supposed to help debugging JNI or native methods. “-verbose:jni” and “-Xcheck:jni” and both arguments when added to the command line for OpenNMS caused the JVM to crash much earlier.

Create the file $OPENNMS_HOME/etc/opennms.conf and add a line ADDITIONAL_MANAGER_OPTIONS=“Xcheck:jni -verbose:jni” and you’ll get the crash.


As Jessie had posted earlier, one of the FreeBSD java port developers is needed to help diagnose it further from here.
