Created attachment 98533 [details] Log files and thread dump in zip file IDE is in a debugging session in a Java EE Web project, but not suspended, still running normally. As a response of the debug session star, the output window correclty highlights some invalid breakpoints. I select all breakpoints and choose the context menu option delete for a cleanup. CPU usage is at 100% for the next 10 minutes. At this stage I create a thread dump and terminate procss netbeans.exe.
Created attachment 98685 [details] Snapshot taken during deletion of breakpoints in current dev build
I've reproduced this problem in current dev build. Deletion really seems to take longer than it has to.
Outline handles node icon and display name changes very inefficiently. It refreshes *whole* table because of a change of *one* icon. Due to that fact even scrolling is slow until all nodes are refreshed! This needs to be fixed in Outline.
Lowering the priority to P3, in current dev builds it does not take so long. Because of the risky nature of issue #185810 this might not be further improved in 6.9.
We need to improve performance of Outline refresh in the next release.
It's fixed by the improvements in event handling - issue #185810. http://hg.netbeans.org/main/rev/c97fab6053e1
