------------------------------------
I haven't looked at this, but since you note that this is blocking your application
usage without any workaround, have you tried explicitly setting something into the MDC
using whatever logging framework you are using? Or is there no chance you can do this
because this happens on an async EJB invocation thread even before it gets to the point
where you can set something?
NullPointerException in LogDiagnosticContextRecoveryInterceptor when
calling an asynchronous EJB
------------------------------------------------------------------------------------------------
Key: WFLY-4198
URL:
https://issues.jboss.org/browse/WFLY-4198
Project: WildFly
Issue Type: Bug
Components: EJB
Affects Versions: 8.2.0.Final
Reporter: Sergiy Barlabanov
Assignee: David Lloyd
When trying to call an asynchronous EJB in a Web application using slf4j (1.7.5+) &
logback(1.0.13+) for logging the following NullPointerException occurs (see below).
The problem is in the line 67 of LogDiagnosticContextRecoveryInterceptor class, when it
tries to access MDC map, which is null. According to SLF4J API the copy of MDC map may be
null: see the javadoc of org.slf4j.MDC#getCopyOfContextMap.
So LogDiagnosticContextRecoveryInterceptor or org.jboss.logging.Slf4jLoggerProvider have
to check the map for null.
Currently there is no workaround for that :(.
Caused by: java.lang.NullPointerException
