Description Petr Pisl 2007-05-31 18:24:32 UTC 
Ubuntu Linux, GTK

Load a head dump
Switch to Instances
Display Size column in the Instance window.
Click on the Size label to sort according size. If there is a lot of instances
or you do doubleclick, you obtain this NPE:

java.lang.NullPointerException
	at javax.swing.JComponent.scrollRectToVisible(JComponent.java:3055)

Doesn't seem to be strictly Linux-related.

*** Issue 105592 has been marked as a duplicate of this issue. ***
Comment 3 Jiri Sedlacek 2007-06-27 15:41:17 UTC 
Caused by invoking sorting subsequently in short intervals. Fixed the NPE.

Fixed for Beta1.
