I'm not sure if there's a reasonable way to test this fix. You can use the Clipboard API w/o creating/showing any top-level windows which would emulate the conditions where the bug is currently reproduced in the browser environment. However, you'll never receive the synthetic focus event then, so the fix won't help in this case I guess...

BTW, did you test compare behavior to Apple JDK? Is it any different there?

Hi Anthony ,

will fix, I thought that chain of method calls is something like code convention. BTW is someone have idea how test can be implemented to this? Thanks, Mikhail. On 29.03.2013 20:10, Anthony Petrov wrote: Hi Mikhail,

The idea of the fix looks good to me. Note that you don't need the -javaCheckPasteboard helper method. There's a method in ThreadUtilities that takes a block as an argument. This way you can call the -checkPasteboard directly from the block right in the JNI method implementation w/o any intermediate methods. -- best regards, Anthony On 3/29/2013 19:43, mikhail cherkasov wrote: Hello all,

Could you please review the following fix: http://bugs.sun.com/viewbug.do?bugid=8010925 http://cr.openjdk.java.net/~mcherkas/8010925/webrev.00/ <http://cr.openjdk.java.net/%7Emcherkas/8010925/webrev.00/> Applet doesn't receive any NSApplication*Notification because it doesn't create any windows, so if we have applet with windows - all works fine. But in this case all content are added to applet's ContentPane that is embedded to browser and hasn't any window. But AWT updates clipboard data only on NSApplicationDidBecameActiveNotification. So if we make copy action from applet , applet will never read new data from system pastboard, it just will use cached data. To fix this I added pasteboard check on CEmbeddedFrame focus receiving. Thanks, Mikhail.
