> Hi All,
> Please review the following fix for jdk17.
> Issue : On MacOS 11 Java Frame and JDialog application is freezing in Full Screen when the System Preference -> General -> Prefer Tabs is set to "Full Screen". It is also freezing in normal screen when Prefer Tabs is set to "Always".
> It doesn't freeze when the Prefer tabs is set to "never".
> Fix : The default value of allowsAutomaticWindowTabbing is 0/NO in MacOS prior to bigSur(11)
> (in the AWTWindow.m file), so the issue is not seen in mac os 10.13 10.14 and 10.15.
> From MacOS 11 onwards this value is set to 1/YES and the issue is seen.
> This issue can also be reproduced in MacOS 10.15 by setting setAllowsAutomaticWindowTabbing to true in the AWTWindow.m file.
> Fix is to set allowsAutomaticWindowTabbing to No for all the MacOS release staring from 10.12.
> The allowsAutomaticTabbing was introduced in MacOS 10.12 but the default value changed in macos11.
> Test : Added a manual test and tested on MacOS 10.15 and 11.
> All the internal tests run are green.
