Illegal reflective access while running simulation in UnetStack

Question

bin/unet samples/2-node-network.groovy running this line throws the following error.

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v7.Java7$1 (file:/home/mohanraju/Documents/Research/unet-community-3.4.0/unet-3.4.0/lib/groovy-2.5.9.jar) to constructor java.lang.invoke.MethodHandles$Lookup(java.lang.Class,int)

java.lang.IllegalArgumentException: object is not an instance of declaring class

Can you put a breakpoint in IllegalArgumentException and see what line of source triggers the exception? — emilles, Oct 22 '22 at 22:31

Sounds like a Java version problem.

Can you check which version of Java you're running by typing the following command in your terminal

java -version

UnetStack v3.x.x only support Java8. You can install it for your https://adoptium.net/temurin/releases?version=8
