I found this in the console (was not in the log; I'll file a bug for jdt.text
that this should be logged). I was experimenting with 1.5 code when this
happened. Sorry, no steps to reproduce.

Comment 1 David Audel CLA 2005-03-30 05:14:43 EST 
Fixed

The line 211 of SelectionEngine must be

System.arraycopy(this.acceptedClassesModifiers, 0, this.acceptedClassesModifiers
= new int[newLength], 0, length);

instead of

System.arraycopy(this.acceptedClasses, 0, this.acceptedClassesModifiers = new
int[newLength], 0, length);
