Android: Assistive Technology not found or SWT.error trying to run ddms

If you’re trying to run ddms from the Android SDK and you get this error:

06:24 E/ddms: shutting down due to uncaught exception
06:24 E/ddms: java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.JavaBridge

OR

08:53:11 E/ddms: shutting down due to uncaught exception
08:53:11 E/ddms: org.eclipse.swt.SWTError: Not implemented [multiple displays]
	at org.eclipse.swt.SWT.error(Unknown Source)
	at org.eclipse.swt.widgets.Display.checkDisplay(Unknown Source)
	at org.eclipse.swt.widgets.Display.create(Unknown Source)

Then you can fix it via:

$ sudo apt-get install openjdk-6-jre

You’re welcome.
