>          Issue Type: Bug
>    Affects Versions: 2.5.15

> Using janino 2.5.15 (not currently unreleased as the 'affects versions' box suggests), trying to access a public member function of a superclass that is package-protected results in an IllegalAccessException.
> For example, trying to use java.lang.StringBuilder's length() method (which is defined in package-protected java.lang.AbstractStringBuilder):
> <code>
>     public static final void main(String[] args)
>     {
>         try
>         {
>             ScriptEvaluator se = new ScriptEvaluator(
>                     "StringBuilder sb = new StringBuilder(); return sb.length();",
>                     Integer.class,
>                     new String[0],
>                     new Class[0]);
>             Object res = se.evaluate(new Object[0]);
>             System.out.println(res.toString());
>         }
>         catch (Exception e)
>         {
>             throw new RuntimeException(e);
>         }
>     }
> </code>
> Using this code results in the following:
> Exception in thread "main" java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
