-----------------------------------------------

             Summary: (7.0.z) Suppressed exception format is not correct
                 Key: LOGMGR-159
                 URL: https://issues.jboss.org/browse/LOGMGR-159
             Project: JBoss Log Manager
          Issue Type: Bug
            Reporter: Bartosz Spyrko-Śmietanko
            Assignee: James Perkins
             Fix For: 2.0.5.Final, 2.1.0.Alpha1


The suppressed exception format is not correct when multiple exceptions are suppressed. Too many causes are printed likely because the circular dependencies are not working correctly.

{code:java|title=Example Reproducer}
final RuntimeException r1 = new RuntimeException("Exception 1");
final RuntimeException r2 = new RuntimeException("Exception 2", r1);
final RuntimeException r3 = new RuntimeException("Exception 3", r2);

final RuntimeException cause = new RuntimeException("This is the cause", r1);
cause.addSuppressed(r2);
cause.addSuppressed(r3);
Logger.getLogger(Main.class).error("Log message", cause);
