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:
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?
