Logback NPE in Felix OSGi container.
I'm hitting an NPE in logger initialization in the Felix OSGi container if I specify the logback.configurationFile system property. Without the system property, I don't hit this and everything logs to the ConsoleAppender as expected. Any suggestions as to how to fix this? java.lang.NullPointerException at ch.qos.logback.core.util.Loader.getResourceOccurenceCount(Loader.java:58) at ch.qos.logback.classic.util.ContextInitializer.multiplicityWarning(ContextInitializer.java:160) at ch.qos.logback.classic.util.ContextInitializer.statusOnResourceSearch(ContextInitializer.java:183) at ch.qos.logback.classic.util.ContextInitializer.findConfigFileURLFromSystemProperties(ContextInitializer.java:111) at ch.qos.logback.classic.util.ContextInitializer.findURLOfDefaultConfigurationFile(ContextInitializer.java:120) at ch.qos.logback.classic.util.ContextInitializer.autoConfig(ContextInitializer.java:148) at org.slf4j.impl.StaticLoggerBinder.init(StaticLoggerBinder.java:85) at org.slf4j.impl.StaticLoggerBinder.<clinit>(StaticLoggerBinder.java:55) at org.slf4j.LoggerFactory.bind(LoggerFactory.java:121) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:111) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:268) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:241) at com.weiglewilczek.slf4s.Logger$.apply(logger.scala:32) at com.weiglewilczek.scalamodules.package$.<init>(package.scala:84) at com.weiglewilczek.scalamodules.package$.<clinit>(package.scala) at com.smiley.validation.create.Activator.start(Activator.scala:22) at org.apache.felix.framework.util.SecureAction.startActivator(SecureAction.java:633) at org.apache.felix.framework.Felix.activateBundle(Felix.java:1822) at org.apache.felix.framework.Felix.startBundle(Felix.java:1739) at org.apache.felix.framework.Felix.setActiveStartLevel(Felix.java:1143) at org.apache.felix.framework.StartLevelImpl.run(StartLevelImpl.java:264) at java.lang.Thread.run(Thread.java:637) CONFIDENTIALITY NOTICE: This e-mail message is covered by the Electronic Communications Privacy Act, 18 U.S.C. §2510-2521 and, together with any attachments, is intended only for the addressee.

In the getResourceOccurenceCount method of the ch.qos.logback.core.util.Loader class, it is assumed that the getResource method of the class loader instance will return a non-null enumeration. This assumption does apparently not hold in Felix. Please enter a bug report so that we can fix the issue. On 13/10/2010 9:18 PM, Mark Protas wrote:
