Hi,

when I'm debugging RCP applications I always got NullPointerExceptions when I'm hovering with the mouse inside the Java editor.

3004: Unexpected error occurred.
  java.lang.NullPointerException
  	at ui.ConstantStringHover.getHoverRegion(ConstantStringHover.java:86)
  	at ui.ConstantStringHover.getHoverInfo(ConstantStringHover.java:62)
  	at org.eclipse.jdt.internal.ui.text.java.hover.BestMatchHover.getHoverInfo2(BestMatchHover.java:148)
  	at org.eclipse.jdt.internal.ui.text.java.hover.JavaEditorTextHoverProxy.getHoverInfo2(JavaEditorTextHoverProxy.java:85)
  	at org.eclipse.jface.text.TextViewerHoverManager$4.run(TextViewerHoverManager.java:166)

Regards,

Heiko

Reproducible: Always

That's not an Eclipse class or package name. It looks like you installed some additional plug-in(s) that cause this.

Steps?

Hi Dani,

I found out by debugging the IDE that the reason for the NullPointerException was the TapiJI plug-in from Google. So the fault isn't indeed at the Eclipse side.

Regards,

Heiko
