[jbosstools-issues] [JBoss JIRA] (JBIDE-24186) Eclipse workspace deadlocking during refresh/rebuild

Mon Apr 3 06:38:00 EDT 2017

     [ https://issues.jboss.org/browse/JBIDE-24186?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Beirti O'Nunain updated JBIDE-24186:
------------------------------------
    Description: 
- Windows 7
- Eclipse Neon.2 (4.6.2)
- Developer Studio 10.3.0

After a workspace SVN update, the rebuild in Eclipse hangs (Eclipse remains responsive for a short time) with the following jobs in the progress pane:

+ "Refreshing '/my-non-j2ee-webproject/target/m2e-wtp/web-resources'"
+ Updating Maven Project (Waiting)
+ Updating Maven Project (Waiting)
+ Updating Maven Project (Waiting)
+ Updating Maven Project (Waiting)
....

The project referenced above is a simple web project with no J2EE or JBoss components, nor is it referenced by any servers in the workspace.

Profiling with yourkit detects a deadlock in the following thread:

Worker-33 <--- Frozen for at least 8m 27s
org.eclipse.wst.server.core.internal.Server.getModules() Server.java:2526
org.eclipse.wst.server.core.internal.Server.visit(IModuleVisitor, IProgressMonitor) Server.java:3035
org.eclipse.wst.server.core.internal.Server$ResourceChangeJob.run(IProgressMonitor) Server.java:228
org.eclipse.core.internal.jobs.Worker.run() Worker.java:55

I started profiling Yourkit when the build hung. It shows the following as the live call stack:

Call Tree	Time (ms)	Level
<All threads>	530944	1
org.eclipse.linuxtools.internal.docker.core.DockerContainerRefreshManager$ContainerRefreshThread.run()	530086	2
org.eclipse.equinox.launcher.Main.run(String[])	436	2
org.eclipse.core.internal.jobs.Worker.run()	421	2

I've not found a workaround yet. Killing eclipse and cleaning the workspace sometimes avoids the issue. This issue does not happen in an Eclipse installation where JBoss tools has not been installed

Eclipse remains responsive until another call to 'Server.getModules' happens. Below is the deadlock trace from when Eclipse completely hangs:

Frozen threads found (potential deadlock)

It seems that the following threads have not changed their stack for more than 10 seconds.
These threads are possibly (but not necessarily!) in a deadlock or hung.
