tim commented on SIMPLEVALIDATION-49:
-------------------------------------

Not sure what it's used for if there's no parent;  perhaps it should go away. 
 At any rate, invocation of 
c.getGraphicsConfiguration().getDevice().getDisplayMode().getWidth() could be 
conditional on there being no parent;  and the result could be cached (it 
would be incorrect if the screen resolution changes, but that's rare enough 
that we might choose not to care, or listen for changes in it if we want to 
be pedantic).

Or, for that matter, just using a value like 1024 or 1280 hard-coded would 
probably be fine enough.

> taking several hundred msec per invocation. Consider whether these calls 
> (e.g. from {{MultilineLabelUI.getMaximumSize}}) are really necessary. The

> this case does it matter what the minimum or maximum size is?
