Since upgrading to Eclipse Photon, it seems to be no longer possible to launch the Marketplace Client when Eclipse theming is disabled. Note that I have tried upgrading to the latest version of MPC via the update site (http://download.eclipse.org/mpc/photon), without any luck. See the following stacktrace:
