#5 Aborting calculations hoses JDBM and more

[Keith Cassell]

I had started to calculate metrics for a large project and clicked the little red square icon to "Abort all ongoing and pending calculations". Afterward, I couldn't get the metrics plug-in to do anything, so I exited Eclipse and restarted. Still nothing. When I looked in .metadata/.log, I saw many errors. The first error on restarting was:
