We've configured -Dappagent.start.timeout=30000 for the java agent for the webapps after we got the issue of Pods getting failed to start due to AppD taking lot of time initially which was delaying liveness probe in EKS. After adding timeout, as per the doc the AppD agent will start in parallel with the application startup reducing the overall startup time. Until few days ago, we started below issue in webapps running on Wildfly server where it is saying java.lang.NoClassDefFoundError: com/singularity/ee/agent/appagent/entrypoint/bciengine/FastMethodInterceptorDelegatorBoot and surprisingly it is giving this error when we remove the timeout configuration. Can anyone confirm if they came across this issue?  9:17:46,228 INFO [stdout] (AD Agent init) Agent will mark node historical at normal shutdown of JVM 09:17:50,323 INFO [stdout] (AD Agent init) Registered app server agent with Node ID[455861] Component ID[6467] Application ID [553] 09:17:56,727 ERROR [stderr] (Reference Reaper #2) Exception in thread "Reference Reaper #2" java.lang.NoClassDefFoundError: com/singularity/ee/agent/appagent/entrypoint/bciengine/FastMethodInterceptorDelegatorBoot 09:17:56,729 ERROR [stderr] (Reference Reaper #2) at org.wildfly.common.ref.References$ReaperThread.run(References.java) 09:17:56,822 ERROR [stderr] (Reference Reaper #1) Exception in thread "Reference Reaper #3" Exception in thread "Reference Reaper #1" java.lang.NoClassDefFoundError: com/singularity/ee/agent/appagent/entrypoint/bciengine/FastMethodInterceptorDelegatorBoot 09:17:56,823 ERROR [stderr] (Reference Reaper #1) at org.wildfly.common.ref.References$ReaperThread.run(References.java) 09:17:56,823 ERROR [stderr] (Reference Reaper #1) Caused by: java.lang.ClassNotFoundException: com.singularity.ee.agent.appagent.entrypoint.bciengine.FastMethodInterceptorDelegatorBoot from [Module "org.wildfly.common" version 1.6.0.Final from local module loader @7a30d1e6 (finder: local module finder @5891e32e (roots: /opt/jboss/modules,/opt/jboss/modules/system/layers/base))] 09:17:56,824 ERROR [stderr] (Reference Reaper #1) at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:200) 09:17:56,824 ERROR [stderr] (Reference Reaper #1) at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:410) 09:17:56,824 ERROR [stderr] (Reference Reaper #1) at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:398) 09:17:56,825 ERROR [stderr] (Reference Reaper #1) at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:116) 09:17:56,825 ERROR [stderr] (Reference Reaper #1) ... 1 more 09:17:56,826 ERROR [stderr] (Reference Reaper #3) java.lang.NoClassDefFoundError: com/singularity/ee/agent/appagent/entrypoint/bciengine/FastMethodInterceptorDelegatorBoot 09:17:56,827 ERROR [stderr] (Reference Reaper #3) at org.wildfly.common.ref.References$ReaperThread.run(References.java) 09:18:05,627 INFO [stdout] (AD Agent init) Started AppDynamics Java Agent Successfully. 09:18:41,038 ERROR [org.xnio.nio] (default I/O-2) XNIO000011: Task org.xnio.nio.WorkerThread$SynchTask@191c0b4b failed with an exception: java.lang.NoClassDefFoundError: com/singularity/ee/agent/appagent/entrypoint/bciengine/FastMethodInterceptorDelegatorBoot ...

Hi, We are running many applications with JAVA_AGENT and out of those, a few applications are discovering the JDBC calls and a few are not discovering the JDBC backend. I even tried to manually add a custom discovery with rule of matching URL. What all other factors impacting this and anything needs to be changed? Have attached the samples here. Note: 1. Both apps are using same version of MySQL connector jar.  mysql-connector-java : 5.1.49 For the application where the JDBC details and queries are captured.  For the similar application where JDBC details are not captured. Note:  1. For the app where details are captured is a web-app where business-transaction are present. but for the app where this is not captured is a core java app without transaction. ( More like a monitoring app ). Does this have any impact? Thanks & Regards. Akshay ... View more
