Created attachment 138934 [details] IDE messages.log The IDE became unresponsive after editing an action in my Maven web project. Prior to the IDE entering this state, I had done the following: 1. I cloned a multi-module Maven project from a GIT repository. 2. I set up a Tomcat 7 web server and associated it with the project. 3. I selected "Run" on the project node. 4. While the "Run" command was executing, I selected "Properties" from the project node. 5. I selected the the "Actions" element and chose to edit the "Run Project" action. 6. I added the property "skipTests=true" and clicked "OK" to exit the dialog. At this point, the IDE displayed a dialog with a progress bar titled "Saving Project data", and it stopped responding to input. An inspection of the Tomcat access log indicates that the requests to deploy and then start the project had both been sent with 200 (OK) response codes. I will attach the thread dump, the IDE log, the UI gestures log.

"Bookmarks loader and saver" and "Default RequestProcessor" threads seem to deadlock. all other threads are waiting for "Default RequestProcessor" thread to release the project write mutex. reassigning to maven/j2ee for evaluation.
