Description

Verbose version of the test passes, but it is a little ugly.

    public static final String FOO_CLASS = "class Foo { int getResult() { return 1; } } ; Foo.class";
    public static final String FOO = "class Foo { int getResult() { return 1; } }";

    public void testClassEvalVerbose() throws ScriptException {
        ScriptEngineManager factory = new ScriptEngineManager();
        ScriptEngine engine = factory.getEngineByName("groovy");
        assertEquals("Foo", ((Class) engine.eval(FOO_CLASS)).getCanonicalName());
    }

    public void testClassEvalBrief() throws ScriptException {
        ScriptEngineManager factory = new ScriptEngineManager();
        ScriptEngine engine = factory.getEngineByName("groovy");
        assertEquals("Foo", ((Class) engine.eval(FOO)).getCanonicalName());
    }

Brief version throws:
javax.script.ScriptException: javax.script.ScriptException: org.codehaus.groovy.runtime.metaclass.MissingMethodExceptionNoStack: No signature of method: Foo.main() is applicable for argument types: ([Ljava.lang.String values: [[]]

Why?
Is this what JSR223 specifies to do?
To sad if yes!
