Darkest Dark
Eclipse Neon 4.6.3 for PHP developers
OS: Windows 7/10.

User installed Darkest Dark and reports that Ctrl+Shift+M, the shortcut for Open Method no longer works and the IDE hangs.

At my end, invoking Ctrl+Shift+M logs unhandled event loop exception silently in the Error Log :

!ENTRY org.eclipse.ui 4 0 2017-10-30 11:23:58.869
!MESSAGE Unhandled event loop exception
!STACK 0
org.eclipse.e4.core.di.InjectionException: java.lang.IllegalArgumentException: Argument not valid

I could replicate the IDE hang reported by the user only when I try to uninstall Darkest Dark plugin and an NPE is logged. I had to terminate the IDE from the Task Manager.

!ENTRY org.eclipse.e4.ui.workbench 4 0 2017-10-30 11:57:43.077

Attached is the user’s log file.
