Unfortunately, I'm still not sure why you're seeing this error but I've seen it once before elsewhere. For example, https://github.com/openmicroscopy/bioformats/pull/170 fixed the issue for Bio-Formats, but I've never seen it under components/insight.

If you would like to open a PR against https://github.com/openmicroscopy/openmicroscopy/, feel free. Otherwise, I'll add fork="true" to those lines and get this into the main build.

Sorry for any troubles, and thanks for bringing it to our attention!

P.S. other things which have partially fixed this issue in particular cases include removing spaces from your JAVA_HOME and/or openmicroscopy.git directories, and removing JREs from your system completely.
