Signed Jar File causes erroneous GUI mode error

[mark_in_gr]

We have discovered that the following message is thrown when a signed jar file is used as a dependency on a Custom Code Action:

Installer User Interface Mode Not Supported

Googling for this error reveals that the error is the result of a JVM incompatibility issue. However, this is NOT the cause in all instances. If a signed jar file is used as a dependency for a custom code action, the error message will be thrown when you launch the installer.

This is a very hard problem to diagnose and a fix should be applied as soon as possible!!!

FYI, this might be a very old issue (almost 3 years!), possible not fixed yet:

LE: After more search I've found another post:

that was pointing to a not supported workaround:

Hope this helps!
