Hello. This is the patch which replaces usages of the old Windows APIs for monitoring clipboard content with new ones introduced in Windows Vista. The deficiencies of the old APIs are well known and might result in some subscribed applications not receiving notifications from the operating system, as they rely on all the applications in the current clipboard chain processing clipboard messages properly. Porting the code to use the new APIs not only makes OpenJDK immune to these issues, but also results in slightly less code needed to support clipboard-related functionality. As this is a change that's very platform-specific, I don't think providing a unit test is practical, as it would also require providing a native application that runs alongside the test and deliberately breaks the keyboard chain, resulting in OpenJDK not being able to receive clipboard format change notifications. This is a bug/limitation of the old Windows API, not OpenJDK itself. Anyhow, the already existing ClipboardInterVMTest passes, which shows that already existing functionality is not impacted by this change.
Kind regards, Daniel
