Bug 448478

Description Christoph Keimel 2014-10-23 08:02:31 EDT

Every buckminster action I start results in an NPE:

The workaround I found to keep my build working was to add the following "empty" property declarations the configuration/config.ini of my eclipse installation.

osgi.configuration.area.default=
osgi.user.area.default=
osgi.user.area=

This should not be necessary, since there are defaults in place when these values are not set.
