Summary:	Debugger tooltip shows NULL on variable when it isn't

Description twolf2919 2008-11-21 18:49:23 UTC

I set a breakpoint on the line after the creation of an object.  When the breakpoint was hit, I hovered the mouse over
the object reference variable and the tooltip said that the variable was NULL.  But, of course it wasn't.  I'm attaching
a screenshot that shows the tooltip and, if you look below, in the "Local Variables" tab, the variable shows having
content (and, of course, on subsequent lines, the code then calls methods on that object).

Someone on the nbusers forum just informed me that the tooltip just shows the object's toString() which, in this case,
returned NULL.  How does one tell from this tooltip:
    appGroup = (com.netforensics.fw.lang.ApplicationGroup) null
that the toString() of ApplicationGroup returned null?   To me, the tooltip implies that appGroup is NULL cast as an
ApplicationGroup object.

Maybe it would be better to have the tooltip say something like:
    appGroup = 0xABCD ["null" from ApplicationGroup.toString()]

So I'm changing issue type to "ENHANCEMENT".
