Created attachment 104698 [details] Thread dump I am using the City.zip sample attached to this article: http://java.dzone.com/articles/getting-started-jpa-and. The steps I did are: 1. Open the project (and resolve the broken library) 2. Open Main.java 3. Ctrl+Click on frmCity. The Go to Declaration "please wait" window with the Cancel button was displayed for a long time (> 10 seconds). I am attaching a thread dump taken during the operation.
