[Swift-devel] Re: coaster-service -passive null pointer exception

[David Kelly]

Attached is the coaster.log that is being generated, but it doesn't contain
much information.

But where it was throwing the exception, I called getStrackTrace() to get
more info and saved it. Hope this helps:

org.globus.cog.abstraction.coaster.service.job.manager.JobQueue.nextId(JobQueue.java:122)
org.globus.cog.abstraction.coaster.service.LocalTCPService.registrationReceived(LocalTCPService.java:58)
org.globus.cog.abstraction.coaster.service.local.RegistrationHandler.requestComplete(RegistrationHandler.java:41)
org.globus.cog.karajan.workflow.service.handlers.RequestHandler.receiveCompleted(RequestHandler.java:84)
org.globus.cog.karajan.workflow.service.channels.AbstractKarajanChannel.handleRequest(AbstractKarajanChannel.java:390)
org.globus.cog.karajan.workflow.service.channels.AbstractStreamKarajanChannel.step(AbstractStreamKarajanChannel.java:158)
org.globus.cog.karajan.workflow.service.channels.AbstractStreamKarajanChannel$Multiplexer.run(AbstractStreamKarajanChannel.java:377)
