[logback-user] janino error upgrading to 0.9.29

We are using logback-classic and logback-core in a tomcat 6.0.32 application. Our logback.xml contains an if condition, so our application classpath includes the following files: janino.jar logback-classic-0.9.29.jar logback-core-0.9.29.jar When we try logback 0.9.29, logback is suddenly unable to find the janino file. Tomcat reports the following error: ERROR in ch.qos.logback.core.joran.conditional.IfAction - Could not find Janino library on the class path. Skipping conditional processing. The problem disappears when we put the logback 0.9.28 files back in place. Is there something new we need to do in .29? Thanks for your help. /mcr
