This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
steps to reproduce: 1. create uml project 2. add component diagram 3. add and name two classes to the diagram 4. draw association class between classes 4a. click on an empty space on the diagram to unselect everything 5. press 'relationship discovery' toolbar button relationship discovery process takes at least 10 seconds on P4-2800/2GB system 6. click on first class it takes few seconds to select class 7. click on operation in class it takes few second to select operation 8. try symmetric layout This performance problem seems to be in any diagram that Association Class can be created. So, it's not limited to just Component Diagram.
Created attachment 31524 [details] diagram layout result
see attached snapshot for the result of doing the symmetric layout.
it isn't a performance issue per se - it is just that a huge amount of extra, duplicating, egdes are generated as a result of relationship discovery (as a result of symmetric layout they form that nice snowflake on the snapshot) Fixed in coco and release55(ie. coke) branches.
