Description Severin Gehwolf CLA 2010-06-22 10:44:32 EDT 
Build Identifier: M20100211-1343

I am using eclipse-* rpm packages. When Eclipse starts up and a spec file is open, I'm getting this error:

An internal error occurred during: "Update RPM packages proposal list".

Stack trace:
java.lang.NullPointerException
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:71)

I'm not sure why this is happening.

Reproducible: Didn't try

Comment 2 Mikhail Kalkov CLA 2011-07-25 12:36:25 EDT 
I am not sure if it is the same bug or not, but I observe a livelock in LinuxTools RPM plug-in on Eclipse 3.6.2 M20110210-1200 win32. The livelock is triggered when I open Specfile Editor page, and looks as a lot of small "Update RPM packages proposal list" jobs, which end only when I shut down Eclipse, and then, the attached stack trace is printed on the console.

From quick code examination it seems that an update job can never succeed because linux utilities are not available on linux, and if a file with job results at PreferenceConstants.P_RPM_LIST_FILEPATH cannot be found, the job is automatically restarted. I think, the same problem could happen on linux in some particular cases when the job cannot succeed for whatever reason.

Comment 3 Alexander Kurtakov CLA 2011-09-06 08:25:33 EDT 
Is this bug reproducible with current master? Looks like I fixed it with some other issues already.
Comment 4 Alexander Kurtakov CLA 2011-09-23 06:24:27 EDT 
No response and I can't reproduce and a bit of stabilization in this area happened fixing quite a few possible problems. Please reopen if it still happens with master and provide an easy way to reproduce.
