Re: JobPoller: Problems reading values from serviceengine.xml file

[Scott Gray]

That's a problem in the older versions caused by concurrent access to the
cached dom model of the serviceengine.xml file. The dom doesn't support
concurrent reads and you'll intermittently see this problem.

The only solution is to store the serviceengine configuration in POJOs
rather than caching the dom.  It's a pain to change because the cached dom
is referenced all over.  I believe Adrian converted it to POJOs in one of
the later versions, you could always try backporting that to your version.
