title: Java Scripting API (JSR223) groovy language limitations
body: <p>I want to know the limitation(s) when executing code using <a href="https://docs.oracle.com/javase/8/docs/technotes/guides/scripting/prog_guide/api.html" rel="nofollow noreferrer">Java Scripting API</a> (JSR223) for example using <code>Beanshell</code> or <code>groovy</code> language,</p>
  
  <p>What <strong>can't</strong> be done/execute using the language chosen as groovy? Is there some language capabilities that can't be used inside script?</p>
