----------------------------------------
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
