log messages from plugin doesn't reach system logger after restart of Jenkins

[esrug]

Hi, 

I have a problem where the logger messages from a plugin stops showing up in a the logger when Jenkins has been restarted.

I am working on an SCM plugin. I have created a class where I instantiate a logger and use it in the methods:

package dimtestplugin;

......

import java.util.logging.Level;

import java.util.logging.Logger;

.......

public class DimoScm extends SCM {

.....

private static final Logger LOGGER = Logger.getLogger(DimoScm.class.getName());

.......

@Override

public SCMRevisionState calcRevisionsFromBuild(AbstractBuild<?, ?> arg0,

Launcher arg1, TaskListener arg2) throws IOException,

InterruptedException {

DimRevisionState revisionState = new DimRevisionState();

//Ask for the time stamp of the latest modification in the repos based on the path

Date latestTimestamp = branch.getLastModificationDateByPath(path);

---> LOGGER.log(Level.FINE,"calcRevisionFromBuild - latestTimeStamp: " + latestTimestamp.toString());

revisionState.setTimeStampOfLastModification(latestTimestamp);

//return object containing the time stamp of the latest modification.

return revisionState;

}

.......

}

In Jenkins I create a logger which is connected to the specific class 'dimtestplugin.DimoScm'. When I create the logger in Jenkins the generated log messages start appearing in the window. So far so good.

Now, if I restart Jenkins the log messages stop appearing in the logger. If I then either create or delete a logger - it can be any of the loggers, it does not necessarily need to be related to my plugin, the messages start showing up again. I have created other loggers which for example logs messages from the Subversion plugin. These loggers doesn't stop working when I restart Jenkins.

I really need this to work because I want to use the log for debugging, and I don't want to have to recreate the logger every time I have created a new version of my plugin and restarted Jenkins.

Any help is much appreciated.

Thank you.

As a workaround
You can define the log level in a static file and configure java to
load that at startup.

Google logging.properties.

I have observed the same behaviour where a logger added in the yo is
lost on restart, I've never seen it kept and didn't think this was
even possible.
