DO NOT REPLY [Bug 47465] New: Reading configuration files from a JAR locks the JAR file

https://issues.apache.org/bugzilla/show_bug.cgi?id=47465

           Summary: Reading configuration files from a JAR locks the JAR
                    file
           Product: Log4j
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Configurator
        AssignedTo: log4j-dev@logging.apache.org
        ReportedBy: markt@apache.org


If a log4j configuration file is found by the classpath search inside a JAR
file, the file will be loaded from the JAR. However, the initial
URLConnection.getDefaultUseCaches() setting means that caching is used and the
JAR file is locked.

This is a particular problem for container environments like Tomcat, as it
prevents a web application from being removed. Whilst the workaround is simple
- don't put your log4j configuration in a JAR - it impacts a large number of
users.

I have a patch and test case for PropertyConfigurator. I still need to test
DOMConfigurator. I will update this bug report with the results of that test
(and a patch if necessary) later today.

Patch and test cases

Test cases to demonstrate the issue and a patch to fix the issue attached.

Note the test cases use files paths that work on my machine. These do not
appear to be consistent with the other test cases so a few tweaks may be
required.
