This is mainly to do with Jira issue GPD-78 http://jira.jboss.com/jira/browse/GPD-78. For some reason i was unable to create an account otherwise I would have re-opened the issue myself.
If someone else is getting the same problem could they re-open this issue.

Basically my process has an a node with an action element like this:

<action class="SomeActionHandler">
 <keys>
 <entry>
 <key>VarName</key>
 <value>1122</value>
 </entry>
 </keys>
 <receive>
 <element>030101</element>
 <element>030102</element>
 </receive>
</action>

protected String getTextContent() {
 StringBuffer buffer = new StringBuffer();
 NodeList list = getNode().getChildNodes();
 for (int i = 0; i < list.getLength(); i++) {
 buffer.append(list.item(i).getNodeValue());
 }
 return buffer.toString().trim();
 }

protected String getTextContent() {
 StringBuffer buffer = new StringBuffer();
 NodeList list = getNode().getChildNodes();
 for (int i = 0; i < list.getLength(); i++) {
 String nodeValue = list.item(i).getNodeValue();
 if (nodeValue != null)
 buffer.append(nodeValue);
 }
 return buffer.toString().trim();
 }
