[Christoph Zauner (JIRA)]

Title: Message Title

Christoph Zauner created an issue   logback / LOGBACK-1125 Enable the use of Janino together with logback in an OSGi environment Issue Type: Improvement Affects Versions: 1.1.3 Assignee: Logback dev list Components: logback-core Created: 29/Jan/16 9:47 AM Environment: logback-core Janino library OSGi environment Priority: Trivial Reporter: Christoph Zauner Problem As stated in the Logback documentation conditional processing in configuration files requires the Janino library. When running in an OSGi environment (e.g. an Eclipse RCP application) simply placing commons-compiler.jar and janino.jar on your application's class path is not sufficient enough. You will get the following exception: <...> 12:50:47,754 |-INFO in ch.qos.logback.classic.joran.action.RootLoggerAction - Setting level of ROOT logger to DEBUG 12:50:47,755 |-INFO in ch.qos.logback.core.joran.action.AppenderRefAction - Attaching appender named [stdout] to Logger[ROOT] 12:50:47,755 |-INFO in ch.qos.logback.core.joran.action.AppenderRefAction - Attaching appender named [file] to Logger[ROOT] 12:50:47,810 |-ERROR in ch.qos.logback.core.joran.conditional.IfAction - Failed to parse condition [property("instance").equals("PRODUCTION_ENV")] org.codehaus.janino.JaninoRuntimeException: Cannot load class 'ch.qos.logback.core.joran.conditional.PropertyWrapperForScripts' through the parent loader at org.codehaus.janino.JaninoRuntimeException <...> Proposed solution The org.codehaus.janino bundle needs a Require-Bundle: ch.qos.logback.core directive in it's manifest file in order for the bundle class loader to be able to load classes from the ch.qos.logback.core bundle. This can be achieved by extending the org.codehaus.janino bundle via a fragment (ch.qos.logback.contrib.logback-janino-fragment). GitHub PR Link to pull request on GitHub implementing this solution.
