[JIRA] Created: (LBGENERAL-30) logback fails to initialise when loaded from bootstrap classpath
logback fails to initialise when loaded from bootstrap classpath ---------------------------------------------------------------- Key: LBGENERAL-30 URL: http://jira.qos.ch/browse/LBGENERAL-30 Project: logback-general Issue Type: Bug Affects Versions: 0.9.14, 0.9.15 Reporter: Henric Larsson Assignee: Logback dev list Attachments: classloader.patch When logback is put in the endorsed library path of the jdk, it fails to initialise because the getClassLoader() call returns null in a couple of places. Returning null is expected when the classloader is the bootstrap classloader, as is the case when logback is loaded from the endorsed directory. Here's a snippet from the sun jdk javadoc for Class.getClassLoader() "Returns the class loader for the class. Some implementations may use null to represent the bootstrap class loader. This method will return null in such implementations if this class was loaded by the bootstrap class loader." I'm using jacorb 2.3.1, which uses slf4j-api 1.5.6. Jacorb is required to be in the endorsed lib to work, and hence any logging implementation has to go there too. I patched my logback instance to return the system classloader when the null classloader is encounterd.
