[Abacn]

What happened?

Due to that Hive 3.1.3 only supports Java8. Specifically, running on Java11 give the following error

java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')
