NullPointerException when committing Docker image [EBZ#512582] -------------------------------------------------------------- Key: ERT-482 URL: https://issues.jboss.org/browse/ERT-482 Project: Eclipse Release Train Issue Type: Task Components: Linux Tools Reporter: Friendly Jira Robot Assignee: Jeff Johnston Labels: Docker, bzira Environment: Windows 7 Eclipse: Neon.1a Release (4.6.1) 20161007-1200 Docker Tooling: 2.1.0.201609141916 Steps to reproduce: 1. Pull latest tomcat (Note: I have no other images or containers in my docker at this time) 2. Run image 3. Commit container 4. This NPE will be shown: An internal error occurred during: "Committing Container to Image". java.lang.NullPointerException at org.eclipse.linuxtools.internal.docker.ui.commands.CommitContainerCommandHandler$1.run(CommitContainerCommandHandler.java:78) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) After this error happened, I restarted my workspace and tried to commit the container again and this time it worked. So it is possible that this happens because I have no images or containers on my docker.
