Null Tracer injected on redeploy of WAR

XMLWordPrintable

    • Hide

      Build a WAR (using enclosed pom.xml) containing just simple class SampleServiceApplication.java 

      and deploy it using Management Console. Everything is fine, a log entry appears - Tracer [class io.jaegertracing.internal.JaegerTracer] registered as global tracer.

      Disable WAR and enable it after a while (5 seconds is enough). A NullPointerException appears in stacktrace:

      {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"sampleservice-1.0.0-0-SNAPSHOT.war\".undertow-deployment" => "org.jboss.weld.exceptions.WeldException: WELD-000049: Unable to invoke private void sampleservice.SampleServiceApplication.doOnPostConstruct() on sampleservice.SampleServiceApplication@1b826106
      Caused by: org.jboss.weld.exceptions.WeldException: WELD-000049: Unable to invoke private void sampleservice.SampleServiceApplication.doOnPostConstruct() on sampleservice.SampleServiceApplication@1b826106
      Caused by: java.lang.reflect.InvocationTargetException
      Caused by: java.lang.NullPointerException: Cannot register GlobalTracer <null>."}}

       

      Tested on WF 21.0.0.Final, may also others are affected.
