Damjan,
I did as you suggested and used the remote debugging to walk through the
static constructor in Launcher. What I discovered was that the constructor
was not finding the mod_java.so file. I tried setting
java.library.pathexplicity in
java.conf.xml and also by rebuilding with -prefix=/usr/local/java. Neither
of these solutions were successful. I was able to verify that this was the
issue by explicitly entering the library path into the code for the Launcher
constructor and running the app. This was successful. I just need to
resolve why the System.getProperty("java.library.path") is failing to
retrieve the library path.
