Description Christoph Laeubrich CLA 2022-02-04 07:37:52 EST 
It fails with:

Caused by: java.lang.IllegalStateException: Workbench has not been created yet.
	at org.eclipse.ui.PlatformUI.getWorkbench(PlatformUI.java:102)
	at org.eclipse.ui.dialogs.ListSelectionDialog.configureShell(ListSelectionDialog.java:412)
	at org.eclipse.jface.window.Window.createShell(Window.java:498)
	at org.eclipse.jface.window.Window.create(Window.java:430)
	at org.eclipse.jface.dialogs.Dialog.create(Dialog.java:1094)
	at org.eclipse.jface.window.Window.open(Window.java:788)

this is because of:
@Override
	protected void configureShell(Shell shell) {
		super.configureShell(shell);
		PlatformUI.getWorkbench().getHelpSystem().setHelp(shell, IWorkbenchHelpContextIds.LIST_SELECTION_DIALOG);
	}

It should either have the opportunity to disable the help or catch the exception.

> org.eclipse.ui.dialogs.ListSelectionDialog.

It is not a JFace element but belongs to eclipse.ui which is free to poke around in the workbench.
