Remote poller dies when trying to use the PageSequenceMonitor

Description

Remote poller aborts when it tries to activate a page sequence poll:

The origin of the problem could be reduced to the following part of the poller-configuration.xml:

This part of the configuration works locally fine - but it fails for remote-polling.

I think that my environment where the RP was crashing had several versions of Java installed that were interacting badly. Once I cleaned up my Java install, I was unable to reproduce this problem.

I think that the main issue here was but now that it is fixed, I don't think there's a problem. I also added some more defensive code to the PageSequenceMonitor so that exceptions caused by invalid configs are caught in case there are unexpected issues in the future.

Marking as fixed in 18.

I think that this issue is the same as which was fixed in OpenNMS 17. I'm going to do some further testing to see if I can replicate the issue but if not, this is likely already fixed.

I misread and didn't realize that this problem was killing the Remote Poller process but that appears to be the case. I've reproduced the problem on my system. Working on a fix.

This might be related to JAXB changes. It's using the newer MOXy library in those stack traces so it might be intolerant of some XML formatting on the remote poller side.

Nope ... it only took a longer time to abort.

Still completely broken: any page-sequence polling kills the remote monitoring site.
