Hello. Please review the fix for jdk9. This is similar to the issue described here: http://mail.openjdk.java.net/pipermail/beans-dev/2015-May/000138.html
The problem is that PropertyDescriptor.getValue() for "enumerationValues" return null, when default enumerationValues is assumed or an empty array was provided by the user. There are a different ways to fix the issue but I select this, because of assumption that @BeanProperty(enumerationValues = {}) should not return null, and we have no way to detect: it was set by the user or by default.
