Description

After creating a simple project by following the instructions here: http://www.itinpractice.com/tutorials/397/struts-2-form-validation-using-xml.html#.Ua9bQpyNBdU I ended up with a working simple xml validator that looks like this:
<validator type="regex">
<param name="fieldname">personBean.phoneNumber</param>
<param name="expression"><![CDATA[\d

{3}-\d{3}

-\d

{4}

]]></param>
<message>Phone number must be entered as 999-999-9999.</message>
</validator>

Changing the struts2-core version in the pom.xml file to 2.3.14.3/2.3.14.2/2.3.14.1/2.3.14 makes the regex no longer return an error. If I change it back to 2.3.4.1, it works as expected.
