 /**

  * Checks for reference to any of the named classes.

  * <p/>

  * The <code>classNames</code> property specifies the comma-separated list of (fully-qualified) class names to check for.

  * The class name(s) may optionally include wildcard characters ('*' or '?'). Note that the '*' wildcard

  * matches any sequence of zero or more characters in the class/package name, e.g. 'a.*.MyClass' matches

  * 'a.b.MyClass' as well as 'a.b.c.d.MyClass'. If <code>classNames</code> is null or empty, do nothing.

  *

  * Known limitation: Does not catch references as Anonymous Inner class: def x = new org.bad.Handler() { .. }
