See issue #201449 for more information.
Warning (with a checkbox "Do not show me again") is displayed once an FTP error happens. This warning says something like "You are perhaps facing problem XY" and it has a link to the JDK issue.
Fixed. Lado, please verify that the warning dialog is displayed when the FTP problem appears. Thanks a lot.
