             Summary: Logging: exceptions are not logged correctly
                 Key: JGRP-1757
                 URL: https://issues.jboss.org/browse/JGRP-1757
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor


When calling
{code:java}
log.error("failure: %s", new NullPointerException("booom"));
{code}, the stack trace of the exception is not shown immediately following the error string:

{noformat}
704 [ERROR] jgroups: failure: %s
java.lang.NullPointerException: booom
        at org.jgroups.tests.bla4.main(bla4.java:14) [classes/:?]
{noformat}

Invoking {{toString()}} on the exception works, but in some cases, we want to be able to see the stack trace.
Investigate how to show the stack trace on all (currently) 3 loggers (JDK, log4j and log4j2).
