Note that the catch clause below constructs an OpenDataException but
does not throw it:

    static class CompositeDataMXBeanType extends MappedMXBeanType {
        final Class javaClass;
        final boolean isCompositeData;
        Method fromMethod = null;

        CompositeDataMXBeanType(Class c) throws OpenDataException {
            this.javaClass = c;
            this.mappedTypeClass = COMPOSITE_DATA_CLASS;

            // check if a static from method exists
            try {
                fromMethod = (Method)
                    AccessController.doPrivileged(new PrivilegedExceptionAction() {
                        public Object run() throws NoSuchMethodException {
                            return javaClass.getMethod("from", COMPOSITE_DATA_CLASS);
                        }
                    });
            } catch (PrivilegedActionException e) {
                // NoSuchMethodException is wrapped
                final OpenDataException ode =
                    new OpenDataException("from(CompositeData) method "
                        + "doesn't exist in " + c.getName());
            }
