SUGGESTED FIX Name: agR10216 Date: 06/26/2003 Synchronize access to the field SunClipboard.currentDataFlavors. ###@###.### 2003-06-26 ====================================================================== Name: agR10216 Date: 07/09/2003 When SunClipboard.checkChange(long[] formats) is called on the toolkit thread on the timeout the passed 'formats' may appear outdated if setContents() is called (on another thread) nearly at that time. So superfluous notification may be sent even if we are synchronizing access to the field SunClipboard.currentDataFlavors. The more reliable fix is to send notifications only from X11Selection.getSelectionOwnership() holding awtLock, which is called in SunClipboard.setContents(), while the JVM is the selection owner. ###@###.### 2003-07-09 ======================================================================

EVALUATION Name: agR10216 Date: 06/26/2003 The test failed because some superfluous notifications about change of data flavors available on the system clipboard were sent. On X platforms when tracking changes of data flavors available on the system clipboard (selection), we call SunClipboard.checkChange(long[] formats) on the toolkit thread at regular intervals and from setContents() on the thread on which setContents() is called. checkChange() sends notifications (PeerEvents) to proper EDTs if available data flavors have been changed. The field SunClipboard.currentDataFlavors, used to store currently available data flavors, is accessed in checkChange(). Access to the field SunClipboard.currentDataFlavors is unsynchronized, and so superfluous notifications may be sent. ###@###.### 2003-06-26 ======================================================================
