Logback fails to configure in OSGI container, when multiple configurations found --------------------------------------------------------------------------------
Key: LBCLASSIC-211 URL: http://jira.qos.ch/browse/LBCLASSIC-211 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: 0.9.20 Environment: Apache felix OSGI container, profiling with JProbe. Sun JDK 1.6.0_17 Reporter: David Riseley Assignee: Logback dev list Priority: Minor
When we attempt to profile our application, which runs in an Apache Felix OSGI container, using JProbe the Logback configuration fails with the following exception: Failed to instantiate [ch.qos.logback.classic.LoggerContext] Reported exception: java.lang.IllegalArgumentException: name at sun.misc.URLClassPath$Loader.findResource(URLClassPath.java:458) at sun.misc.URLClassPath$1.next(URLClassPath.java:195) at sun.misc.URLClassPath$1.hasMoreElements(URLClassPath.java:205) at java.net.URLClassLoader$3$1.run(URLClassLoader.java:393) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader$3.next(URLClassLoader.java:390) at java.net.URLClassLoader$3.hasMoreElements(URLClassLoader.java:415) at sun.misc.CompoundEnumeration.next(CompoundEnumeration.java:27) at sun.misc.CompoundEnumeration.hasMoreElements(CompoundEnumeration.java:36) at sun.misc.CompoundEnumeration.next(CompoundEnumeration.java:27) at sun.misc.CompoundEnumeration.hasMoreElements(CompoundEnumeration.java:36) at ch.qos.logback.core.util.Loader.getResourceOccurenceCount(Loader.java:58) at ch.qos.logback.classic.util.ContextInitializer.multiplicityWarning(ContextInitializer.java:131) at ch.qos.logback.classic.util.ContextInitializer.statusOnResourceSearch(ContextInitializer.java:154) at ch.qos.logback.classic.util.ContextInitializer.findConfigFileURLFromSystemProperties(ContextInitializer.java:88) at ch.qos.logback.classic.util.ContextInitializer.findURLOfDefaultConfigurationFile(ContextInitializer.java:97) at ch.qos.logback.classic.util.ContextInitializer.autoConfig(ContextInitializer.java:119) at org.slf4j.impl.StaticLoggerBinder.init(StaticLoggerBinder.java:83) at org.slf4j.impl.StaticLoggerBinder.<clinit>(StaticLoggerBinder.java:54) at org.slf4j.LoggerFactory.getSingleton(LoggerFactory.java:230) at org.slf4j.LoggerFactory.bind(LoggerFactory.java:121) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:112) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:275) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:248) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:261) at com.example.csp.gui.interfaces.logger.ABCDGUILoggerImpl.getLogger(ABCDGUILoggerImpl.java:74) at com.example.csp.gui.interfaces.logger.ABCDGUILoggerFactory.getLogger(ABCDGUILoggerFactory.java:51) at com.example.csp.gui.kernel.util.ABCDGUIKernelUtil.<clinit>(ABCDGUIKernelUtil.java:61) at com.example.csp.gui.kernel.context.impl.ABCDGUIKernelContextImpl.setAppBaseBundleInContext(ABCDGUIKernelContextImpl.java:207) at com.example.csp.gui.kernel.context.impl.ABCDGUIKernelContextImpl.init(ABCDGUIKernelContextImpl.java:93) at com.example.csp.gui.kernel.context.impl.ABCDGUIKernelContextImpl.<init>(ABCDGUIKernelContextImpl.java:58) at com.example.csp.gui.kernel.activator.impl.KernelActivatorImpl.start(KernelActivatorImpl.java:101) at org.apache.felix.framework.util.SecureAction.startActivator(SecureAction.java:589) at org.apache.felix.framework.Felix.startBundle(Felix.java:1458) at org.apache.felix.framework.Felix.setActiveStartLevel(Felix.java:984) at org.apache.felix.framework.StartLevelImpl.run(StartLevelImpl.java:263) at java.lang.Thread.run(Thread.java:619) SLF4J: Class path contains multiple SLF4J bindings.

After which we get no logging at all. I appreciate that this will be difficult to reproduce , and I think may be related to the "bundle://" URL format not being recognised, so I had a look at the code in ch.qos.logback.classic.util.ContextInitializer.multiplicityWarning() Currently it catches an IOExeception when calling Loader.getResourceOccurenceCount(), however from the stack trace this can also throw an. IllegalArgumentException So could : try { urlList = Loader.getResourceOccurenceCount(resourceName, classLoader); } catch (IOException e) { sm.add(new ErrorStatus("Failed to get url list for resource [" + resourceName + "]", loggerContext, e)); } Become: try { urlList = Loader.getResourceOccurenceCount(resourceName, classLoader); } catch (Exception e) { sm.add(new ErrorStatus("Failed to get url list for resource [" + resourceName + "]", loggerContext, e)); } I did try this in our environment , and the logging did get successfully configured after this change ( although it wasn't pretty.... :-> )
