Kepler

I've been getting an error during the first launch after an ant clean-cache when using the wrp suite, to do with missing ontologies. It turns out my ontology_catalog.xml file was pointing to old paths that no longer exist on my disk. My guess is I renamed(moved) my kepler directory after this file had been serialized by kepler, using absolute paths. I reverted to the repository version of onotlogy_catalog.xml (which just has filenames, not paths) and am now fine.

This raises a larger issue -- it would probably be good to have a test in place that tries moving the kepler application directory after kepler's been in use for awhile, and see if anything breaks.
