Ever since I updated my Java version (around 3 updates ago) it stopped opening .jar files on my computer. I get a pop-up that says:

“The java jar file could not be launched check the console for possible error messages.”

The console says:

Print screen with the log from the console

I am using Java version 10.0.2, and I am completely stuck. It was working just fine before the updates, I was able to create .jar files and open them just fine, but now even if I download external .jar files from the internet I keep getting this message.

Does anyone have any idea how can I fix it?


A .jar file is an applet. The last version of Java to support applets is Java 8.
