             Summary: BootstrapLogManager should first check if there's already a handler
                 Key: KARAF-3710
                 URL: https://issues.apache.org/jira/browse/KARAF-3710
             Project: Karaf
          Issue Type: Improvement
          Components: karaf-core
    Affects Versions: 3.0.3
            Reporter: Raúl Kripalani


BootstrapLogManager should first check whether there are already handlers associated to the JUL logger. If so, it should not create a new one.

We have a situation where the SimpleFileLock is configured with a start level threshold of 55, therefore ops4j pax logging has already initialised and it has taken over JUL through its JdkHandler.

Then comes the BootstrapLogManager and decides to add a new Handler, despite the fact that there is already a root handler configured in JUL.

This leads to two handlers on the SimpleFileLock logger: pax logging's {{JdkHandler}} and Karaf's {{BootstrapLogManager.SimpleFileHandler}}.

The latter is not even configurable by means of a java.util.logging.properties (to my knowledge).

I think that the BootstrapLogManager is no longer necessary, given that Karaf comes bundled with ops4j pax logging OOTB.
