So another approach. As the agent idea is not well received, I tried to reproduce the problem with a plain JTextArea and a flavor listener. The problem is not reproducible there. So it is not just the flavor listener. Based on @xxDark analysis and @mbien idea to rebuild the JDK I augemented a JDK build with logging of the `WClipboard#openClipboard` and `WClipboard#closeClipboard` calls, including the stack traces. I indeed saw two calls running in parallel, one from the native callback listening for clipboard changes and one coming from NetBeans copying data. The latter came from `org.openide.text.QuietEditorPane.DelegatingTransferHandler.exportToClipboard(JComponent, Clipboard, int)`. At that point the editor directly accesses the system clipboard and tries to export data. Given, that NetBeans has an abstraction called `ExClipboard` with the implemention `NbClipboard`, which goes to great lengths to retry copying, I created: https://github.com/apache/netbeans/pull/8394 with that I get this result from the reproducer:  The reference from `master` showed many gaps on the `notepad.exe` side. It would be great if others (@istinnstudio, @xxDark, @bradvido) could test the nightly available from: https://github.com/apache/netbeans/suites/36719959239/artifacts/2885407474 Two comments: - there are other areas in the codebase that make calls to the clipboard, which might also need similar treatment for a complete fix, but the editor is the biggest pain point IMHO - this might(!) fix clipboard history partly, as it routes the copy operation through `NbClipboard` (untested!!!!)
