Possibly my groovy version 1.7.5 was an mistake by myself because some of my reports only work with 1.7.5.
Must upgrade my reports and test with beta groovy version.

Whatever is busted, I only have one groovy JAR on my 1.11 system (groovy-1.9.0-beta-3.jar). Are you sure that the groovy-all-1.7.5.jar has been installed by the current packages? Maybe it is lint from a previous install. Marking as fixed.

Maybe we can test the Remote Poller with Groovy 1.8.6 and use this version for both, the remote poller and the selenium monitor.

BTW, from Junit's point of view, the tests for the BSF Detector also depends on Groovy.

The new Selenium Monitor depends on Groovy 1.9.0-beta-3 (BTW, I've tested the Selenium Monitor with the latest stable version of groovy, 1.8.6, and it works great).

There is only one component which depends on Groovy version 1.7.5, and it is the Remote Poller. For this particular case, the JAR groovy-all-1.7.5.jar is embedded inside $OPENNMS_HOME/bin/remote-poller.jar, so I don't see why that JAR exists on $OPENNMS_HOME/lib, maybe because of a packaging issue for the Debian distribution.

I don't know why Jasper is complaining about that version of Groovy. Never seen that before. Are you using Groovy as the default language for those Jasper Templates ?

Have you tried with only the JAR for 1.9.0-beta-3 in lib/ ? Technically this is the only JAR that should exist on lib/

Some custome reports not working with beta version of groovy (or newer one).
Move groovy-1.9.0-beta-3.jar from lib to does not load at startup and restart opennms only with groovy-all-1.7.5.jar reports running fine.
Is groovy-1.9.0-beta-3.jar required and can be deleted from lib dir?

Generating custom report raise following error:
