[JENKINS-9017] sporadic : ClassCastException for Maven Pom parsing phase on node - Jenkins Jira

protocol7b added a comment - 2011-03-14 10:37

This issue is currently heavily affecting our installation at ASF. Sometimes slaves seems to get stuck and will throw this exception on most builds. Restarting the slave will temporarily fix the problem.

Would be great to get a fix for this quickly.

Indeed... it's causing quite a few issues at ASF. A fix would be much appreciated!

This happens in a number of projects, such as:

It doesn't seem to happen on particular slaves only, and it doesn't always happen.

I had the issue with 1.404, disconnect/reconnect of the slave solved it (for now).

Any progress on this. We're still getting hit quite hard over at ASF with slaves getting stuck with these every day.

Still happening on most of our slaves over at ASF. We're running with slaves disconnecting when idle as a semi-workaround but is in a real need for a fix.

Problem is hitting ci.jenkins-ci.org too (since yesterday) :
First build problem (for me) was : http://ci.jenkins-ci.org/job/plugin-compat-tester/93/console

It is reproductible, for the time being ... just relaunch a build of the plugin-compat-tester and you will reproduce the problem.

[FIXED JENKINS-9017]
Fixed incorrect de-allocation of a classloader from the exported object
table.

The fix is a defense-in-depth; it prevents classloaders referenced in
the object graph from doubly released, then we also make it impossible
for bugs like this to deallocate the key classloader.
