Description Liang Xu 2012-04-11 15:20:11 UTC
We upgrade the openjdk on Freebsd8 from 6 to 7. Now when the remote debug is enabled, the JVM cant start and throw following errors:
Apr  5 16:08:56 TPC-D16-14 appsrv[90192]:
Apr  5 16:09:06 TPC-D16-14 appsrv[90192]: Launching a JVM...
Apr  5 16:09:06 TPC-D16-14 appsrv[90192]: JVM exited while loading the application.
Apr  5 16:09:06 TPC-D16-14 appsrv[90192]: NPT ERROR: Cannot open library

It turns out to be on library no found by the JVM. Then, I find a workaround by creating a link under /usr/local/lib/
ln -s /usr/local/openjdk7/jre/lib/amd64/libnpt.so /usr/local/lib/libnpt.so


How-To-Repeat: 1. Install openjdk7
2. enable remote debug
3. java program fail to start

This also happens on FreeBSD 9-STABLE/amd64.

Seems to be that it also happens in latest openjdk6-b25_1.
Comment 3 yerenkow 2012-11-15 13:50:56 UTC
Actually this should be easily fixed in our javavmwrapper;

tryJavaCommand () {

should check if we are trying to run openjdk7's java, and simply made:

  export LD_LIBRARY_PATH=/usr/local/openjdk7/jre/lib/amd64:$LD_LIBRARY_PATH

then all goes well (it seems so).

Hi Greg,

I noticed that you've picked up this PR (yay!). Would it be too much
to hope that you've managed to find the cause for it and a possible
fix? Or is the javavmwrapper work-around the only recourse for now?

This is now appears to be working with openjdk-7.45.18, on 
amd-64/9.2-STABLE r258726.

I just ran into this on 9.2/amd64:

openjdk-7.51.13_1,1            Java Development Kit 7
javavmwrapper-2.4_3            Wrapper script for various Java Virtual

While using maven to build apache tika.
