Running the Spotfire Server Configuration Tool on a local computer may fail with "A JNI error has occurred, please check your installation and try again" error.

You may run into following error while running uiconfig.bat script locally:

The error states that spotfireconfigtool.jar was compiled at a higher version of Java ( JDK 11) than the version with which you tried to run it. More specifically, in this case, you tried to run it with Java 8, which causes it to fail.  To resolve the issue, uninstall 1.8 version that is currently installed on your local computer and download JDK version that matches the version of Java used by your Spotfire Server.
