SAP MII workbench issue - copy and paste not working, yellow triangle showing

Hi community, I got trouble with MIII workbench. For some (not all) of our MII systems I get a yellow triangle with exclamation mark showing up in the upper right corner of the workbench. It seems to be linked to some Java issue.

Once that triangle shows up some functions like copy and paste will not work anymore.

Running MII 15.0, got Windows 10 on my machine and Java 8/60.

Any ideas on how i can troubleshoot what is the root cause?

    You are running your web start application (SAP MII Workbench) in sandbox or more specifically untrusted mode:

    This typically happens if you have deployed a custom action that you didn't sign first or the signature of the self-signed .JAR has expired. Steps to sign an action are here:

    Just sign the .JAR file (and any dependency JARs) and then redeploy them. Clear your Java Web Start cache and then open the workbench again and the "sandbox" mode should be gone. Hopefully this helps,
