Kernel doesn't work with script engines that don't support Compilable #14

Trying to use Lucee Server which is a JIT compiled JVM scripting language. The Compilable interface is documented as being optional, but this kernel seems to assume that all scripting engines will support it.

Exception in thread "Thread-6" java.lang.ClassCastException: lucee.runtime.jsr223.ScriptEngineImpl cannot be cast to javax.script.Compilable
