    assertEquals("@org.springframework.expression.spel.IndexingTests$FieldAnnotation java.lang.String[]", expression.getValueTypeDescriptor(this).toString());
    assertEquals(property, expression.getValue(this));
    expression = parser.parseExpression("property[0]");
    assertEquals("bar", expression.getValue(this));
}
