Possible regression reproducible on Eclipse IDE for Java Developers 2019-09
Does not occur on earlier versions of Eclipse or at least on Eclipse IDE for Enterprise Java Developers 2019-09

After installing an extension and switching to our tool custom perspective I do not see our wizards on Package Explorer view page if there is no project in workspace. It looks like wizards are correctly registered and available from menu File -> New. Things back to normal after restarting Eclipse.

Despite the comment ('update the list of available project wizards and refresh empty area") the method EmptyWorkspaceHelper.perspectiveActivated(..) does not  update the list of available wizards to display. Once cached while Eclipse starting are present in projectWizardActions collection field until dispose() is called.

Maybe method EmptyWorkspaceHelper.recreateEmptyArea() should null projectWizardsActions to force re-read wizards? btw. there is another misleading comment, saying that the method re-reads the project wizards. 

	private void recreateEmptyArea() {
		disposeEmptyArea();

                //PROPOSED ADDITION
                projectWizardActions = null;

		// re-read the project wizards and re-create the empty area
		createEmptyArea(displayArea);
		if (control != null && !control.isDisposed()) {
			emptyArea.setBackground(control.getBackground());
		}
	}
