Type: Bug
Resolution: Done
Priority: Major
Fix Version/s: jboss-fuse-6.2-patches, fuse-6.x-GA
Affects Version/s: jboss-fuse-6.2.1, jboss-fuse-6.3
Component/s: Fabric8 v1, Karaf

Steps to Reproduce:
Hide

Unpack, configure and start a JBoss Fuse instance

Create a fabric

In a separate window / terminal, open a client session with the bin/client script

Open the resource editor to edit a profile resource, like:
> profile-edit --resource org.ops4j.pax.web.properties default

From another terminal, kill the client session while the editor is still open

CPU usage begins to climb

Use the high_cpu_linux_jstack.sh script to take a thread dump of the container

Note that an orphan thread similar to the one above will be using 90-100% CPU

Description

If a Fuse / Karaf client session is interrupted or killed while the profile editor is open, the reader thread for the resource editor remains RUNNABLE in org.jledit.jline.InputStreamReader.read and CPU usage spikes to nearly 100% - almost all consumed by this thread. The thread does not seem to exit until the container is restarted.
