Unable to create class 'org.eclipse.e4.ui.swt.internal.gtk.DarkThemeProcessor'

Something similar was spotter in upstream: https://bugs.eclipse.org/bugs/show_bug.cgi?id=538597, https://bugs.eclipse.org/bugs/show_bug.cgi?id=538564.

Most closer explanation is at: https://bugs.eclipse.org/bugs/show_bug.cgi?id=539655.

Simply, there seems to be missing org.eclipse.equinox.ds bundle.

Adding the plugin here resolved the issue.
