This may have something to do with me letting the Oomph Preference Recorder open all preferences pages. After that, I cannot open the Network Connections page due to the above exception(s).

FWIW, cannot reproduce these steps with a fresh install and a clean  ~/.eclipse/org.eclipse.oomph.setup/setups (in case Oomph had anything to do with it).

This is bug 479075.  Do you have Gradle/Buildship installed?

> This is bug 479075.  Do you have Gradle/Buildship installed?

Yes, the Java EPP package has Buildship 1.0.7 included, although AFAICT comment ten on Bug 486870 suggests that 1.0.8 with a bugfix should already have been contributed to Mars.2 RC3.

Will reopen *that* bug to bring this to the attention of the Buildship committers, closing this bug as duplicate.
