I want to run some .jar files with openJDK 13.0.2. To run them, i use java -jar nameGoesHere.jar via cmd (Windows 10)

For one .jar i get: 

java.lang.NullPointerException

An other one shows me:

Error: Could not find or load main class ClassNameGoesHere
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

When Using java 1.8.0_241 the .jar files run as expected.

I can not figure out what causes these problems. Any suggestions?

  • You need to add the missing depencies which were bundled in Java 8 when you execute your jar with Java 13. – sigur Apr 14 '20 at 14:16

From JavaFX comes with JDK 8? and Is JavaFX supported in Openjdk? you can see that JavaFX is bundled with JDK 8, but to get it working with OpenJDK you need to follow some instructions.
