          • Environment:
            Load a document page that takes a long time to initialize. Close the document immediately after opening. The viewer RI will appear to hang until the page(s) are done loading. Capture a stack trace to see the lock issue.

            Description

            A client has reported a thread lock issue when trying to close a document that contains pages that take a long time to initialize. See attached stack trace. The report is valid.

            When a page is loaded the page initializer thread gets a lock on the Page object. When the awt-event thread gets the command to dispose the document it can't call page.removePaintPagelistener because of the page initializer lock. Moving the add/removePaintPageListeners synchronization to the vector object gets around this issue.
