Requesting to review the changes mentioned in the trailing mail. It's a backport from Jdk-11 to Jdk-8. Backport is almost clean and there is one line difference in the test file compare to Jdk-11.
Awaiting response.

There is a better way to resolve this by calling ShowScrollBar() and maintain the set size of the scroll bar without resetting it. Since the code that does this job is present in cpp files which calls the native api's, they need to be updated to accommodate this fix which fixes the JBS bug. Hope this answers your question and do have a good day. Thanks and regards, Shashi On 19/03/18 2:05 PM, Patrick Chen wrote: Hi, I am not to understand why ScrollPane.cpp was changed ?

The only difference between JDK 11 changeset and JDK 8 backport is the test file (ScrollPaneValidateTest.java), not awt_ScrollPane.cpp. I had mentioned that in my previous mail. If at all there is any concern related awt_ScrollPane.cpp file then I think that should be dealt after filing another issue. Moreover I didn't really get your question. Out of two nested if blocks, one has been removed and yes, variables are being used and their declarations are still intact. Please let me know if you need any more info.

Means : the two variables are used isn't it ?

Related Jtreg tests have been run against the proposed patch and results are fine. Thanks, Dipak
