Subject [jira] [Created] (LOG4J2-373) Classloader issue in OSGi-environment
Date Tue, 27 Aug 2013 07:19:53 GMT
Roland Weiglhofer created LOG4J2-373:
----------------------------------------

             Summary: Classloader issue in OSGi-environment
                 Key: LOG4J2-373
                 URL: https://issues.apache.org/jira/browse/LOG4J2-373
             Project: Log4j 2
          Issue Type: Bug
          Components: API, Core
    Affects Versions: 2.0-beta9
         Environment: OSGi R5 / R4 (Apache Felix 4.x)
            Reporter: Roland Weiglhofer
            Priority: Critical


Using Log4j2 in a bundle causes following error:
ERROR StatusLogger org.apache.logging.log4j.core.impl.Log4jContextFactory does not implement
org.apache.logging.log4j.spi.LoggerContextFactory
ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogger

printing the ClassLoaders in LogManager gives me following output:

org.apache.logging.log4j.spi.LoggerContextFactory loaded by org.apache.logging.log4j-api [13]
org.apache.logging.log4j.core.impl.Log4jContextFactory loaded by sun.misc.Launcher$AppClassLoader@35a16869

We have two different ClassLoaders. That's why the implementation is not assignable. The core
uses the bootstrap-classloader and the api uses the bundle-classloader.

Workaround needed. Thx
