Caused by: java.lang.NoClassDefFoundError: com/singularity/ee/agent/appagent/entrypoint/bciengine/FastMethodInterceptorDelegatorBootCause
The OSGi boot delegation is not configured correctly and is causing the startup to fail.
Solution
Update the
JVM_SUPPORT_RECOMMENDED_ARGSvariable (in the_start-webapp.sh/_start-webapp.batfile located in$BITBUCKET_HOME/bin) by adding theatlassian.org.osgi.framework.bootdelegation.extraoption with the following value:
1
-Datlassian.org.osgi.framework.bootdelegation.extra=com.singularity.*Restart Bitbucket Server
After applying this change, your JVM_SUPPORT_RECOMMENDED_ARGS variable may look something like:
1
JVM_SUPPORT_RECOMMENDED_ARGS="-javaagent:/path/to/appdynamics/java-agent/javaagent.jar -Dappdynamics.agent.tierName=SOMETHING_HERE -Dappdynamics.agent.nodeName=SOMETHING_HERE -Datlassian.org.osgi.framework.bootdelegation.extra=com.singularity.*"If using the above example, be sure to add any other needed settings (based on your team's existing settings for this variable), as well as modify the above-Dappdynamics.*and-javaagentarguments to match your company's desired values.
