[dd.trace 2020-10-03 21:15:17:942 -0400] [spring-startup] ERROR datadog.trace.agent.tooling.HelperInjector - Error preparing helpers while processing class com.atlassian.plugins.impl.servlet.AdminServlet for Servlet3Instrumentation. Failed to inject helper classes into instance com.atlassian.plugins.static-assets-url [113]
java.lang.IllegalStateException: Error invoking (accessor)::defineClass
at net.bytebuddy.dynamic.loading.ClassInjector$UsingReflection$Dispatcher$UsingUnsafeInjection.defineClass(ClassInjector.java:922)Cause
Datadog Java agent fails to inject helper classes into Bitbucket packages causing git hook to fail and impacting clone operations.
Solution
Workaround
Remove Datadog JVM parameters, shown below, from the instance and restart Bitbucket;
These parameters are usually set in the <Bitbucket_Install>/bin/_start-webapp.sh
1-javaagent:/opt/dd-java-agent.jar -Ddd.profiling.enabled=true -Ddd.logs.injection=true -Ddd.service=<SERVICE_NAME> -Ddd.env=<ENV> -Datlassian.org.osgi.framework.bootdelegation.extra=datadog.*
If needed, engage with Datadog Support for further details and troubleshooting.
