Hi Martin,
The deadline for JDK 11.0.2 is Sunday 28 October !
I suppose this patch will not be reviewed and backported soon... ��
AWT experts, what do you advice about asynchronous events: to Block or to
dispatch selected awt events...
See my mail sent on Thu, Oct 18, 2018 at 4:35 PM.
Cheers,
Laurent
