[JAVA] "Do not show again" check does not work in the warning dialog when starting applet

Premise / What you want to achieve

The "Do not show again" checkbox is displayed in the warning dialog when starting applet, but even if you check it and execute it, the same warning dialog will be displayed the next time it is displayed. I would like to check it so that the warning dialog will not be displayed next time.

It is possible to hide the warning dialog itself, but after investigating so far, we are aware that the latest JDK (1.8.0_121) cannot be used. If you know how to hide the dialog itself, I would appreciate it if you could teach me that too.

Thank you for your cooperation.

Problems / error messages that are occurring

When you start applet by jnlp of the current construction, the warning dialog of the attached image is displayed.

In the red frame of this dialog, "Applications from the above publisher and location will not be displayed from the next time (D)" I checked the checkbox of and clicked the "Run" button to start it normally, but even if I start the same applet again, the same dialog is displayed every time and I am in trouble.

It is recognized that the following work is done correctly to display this dialog. ・ Issuing a valid certificate from a trusted certificate authority -Specify the attribute authority of the file manifest

What I tried

I tried the following, but the warning dialog was hidden and the checkboxes did not work effectively.

■ Trial in Java Control Panel ● "Security" tab -Added the corresponding URL to the "exception site list"

● "Details" tab -Check "Enable-Execute with protection without displaying warning" for "Mixed code (execution in sandbox vs. trusted) security verification" ・ "Execute signed code certificate execution check" "Do not check"
