Resolution
The syslog-ng application uses libjvm.so to embed a Java Virtual Machine inside syslog-ng. Java libraries tend to have a large binary footprint, even just the Java Runtime Environment (JRE) part of it. This is why Java is not bundled with syslog-ng: it would multiple the size of the syslog-ng package. Instead, syslog-ng uses the Java installed on the host. The syslog-ng Premium Edition (PE) supports only Oracle Java 1.7 or later. Oracle Java is used both for development and testing of syslog-ng Java destination drivers.
RESOLUTION 1:
1 - Use the following command to locate the Java library on the system find /usr -name libjvm.so
2 - Review the file /opt/syslog-ng/etc/environment and check the JAVA_LIBRARY_PATH and the LD_LIBRARY_PATH is correct.
Example:
JAVA_LIBRARY_PATH="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.45-30.b13.el7_1.x86_64/jre/lib/amd64/server"LD_LIBRARY_PATH="$JAVA_LIBRARY_PATH:$LD_LIBRARY_PATH"
3. If changes have been made in step 2 you must restart syslog-ng.
RESOLUTION 2:1. Install Oracle Java 1.7 or higher
2 - Uninstall and re-install syslog-ng PE which will automatically find libjvm.so.
