Robert Gemmell commented on QPID-1482: -------------------------------------- Whilst investigating this issue I was given the runaround by another issue, whereby the broker would report the following exception instead of the one listed above. GenericConnectorServer ClientCreation.run WARNING: Failed to open connection: java.lang.NullPointerException java.lang.NullPointerException at com.sun.jmx.remote.generic.ProfileServerFactory.getProvider(ProfileServerFactory.java:272) at com.sun.jmx.remote.generic.ProfileServerFactory.createProfile(ProfileServerFactory.java:220) at com.sun.jmx.remote.opt.security.AdminServer.connectionOpen(AdminServer.java:206) at com.sun.jmx.remote.generic.ServerSynchroMessageConnectionImpl.connect(ServerSynchroMessageConnectionImpl.java:98) at javax.management.remote.generic.GenericConnectorServer$ClientCreation.run(GenericConnectorServer.java:443) at com.sun.jmx.remote.opt.util.ThreadService$ThreadServiceJob.run(ThreadService.java:248) at com.sun.jmx.remote.opt.util.JobExecutor.run(JobExecutor.java:99) A lot of debugging later and examining open source code from the OpenJVM and the OpenDMK (the exception was occurinng within the jmxremote_optional.jar's class files), I devised a workaround in setting the "jmx.remote.profile.provider.class.loader" property within the environment map used by the broker to start the JMXMP connector server. Shortly after that, i found the real solution - it was my use of Eclipse to launch the broker to debug the authentication issue which was itself causing this issue.
