Labs java jars getting an error

hi @Inderpreet @vijin.palazhi

I have correctly installed java 13 and set the environment variable. I see the preset at /opt/app. why is this throwing an error?
Error message: Compile java code correctly on host01 under /opt/app directory?

Yes. This seems to be an issue. Same happened with me, though the file got compiled to MyClass.class and was able to run it.

It works fine now so you can try again .
