Bug#865354: java.lang.NoClassDefFoundError: org/apache/tomcat/InstanceManager

[Emmanuel Bourg]

Thank your for the report Joe. The InstanceManager class is in
/usr/share/java/tomcat8-api.jar. It looks like this jar is missing from
the classpath used by Eclipse. Did you use the version of eclipse
currently in testing/unstable?
