Category: Interactions Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Corey Shaw (sigma_lmtd) Assigned to: Nobody/Anonymous (nobody) Summary: Interactions pane hangs, throws NullPointerException Initial Comment: I was trying some commands in the interactions pane, and one of them it hung. I could not provide any more input into the interactions pane (it had an hourglass), and when I tried to reset, it threw a NullPointerException and caused 20 errors. It looks like the errors are related to the swing components. The same command works fine after I restart DrJava. java.lang.NullPointerException at javax.swing.text.BoxView.paintChild(BoxView.java:144) at javax.swing.text.BoxView.paint(BoxView.java:407) at
