If program generate very tall Swing tooltip (taller than screen 
resolution), on Windows 7, Aero switch off and only come back on once 
Java application is close.

Is this intended behavior? Is known bug or have known workaround? All 
Java version I tried (1.6, 1.7) have this.

Could add code to limit tooltip lines and replace rest with "...", but 
then, different display or font will have different limit before Aero 
problem happen. Would need to add preference setting for users, and would 
still get many support call about it when limit set too high for 
particular workstation. Would cause more confusion than it solve, I 
think. Cleaner would be if tall tooltip not cause problem in first place. 
Though also, then only middle of tooltip visible, when only top would be 
better.

For now I may limit tooltip to 10 lines regardless of underlying data. 
But cleaner solution wanted if possible.
