Marek Went commented on XFIRE-847:
----------------------------------
I noticed the same error, however it does not happen, when only Stax is used.
Once DomIn/DomOutHandler is introduced (for security purpose) the same error
occurs.
Temporary solution is based on 1.2.2 (code below):
org.codehaus.xfire.aegis.stax.ElementReader
public String getValue()
{
if (value == null)
{
try
{
value = root.getElementText();
while (checkHasMoreChildReaders()) {}
}
catch (XMLStreamException e)
{
throw new XFireRuntimeException("Could not read XML stream.",
e);
}
}
if (value == null)
value = "";
return value.trim();
}
> Empty element value can cause NPE

> Key: XFIRE-847
> URL: http://jira.codehaus.org/browse/XFIRE-847
> Project: XFire
> Issue Type: Bug
> Affects Versions: 1.2.3, 1.2.4
> Reporter: Dan Diephouse
> Assigned To: Dan Diephouse
> Fix For: 1.2.5
>
>
> From the mailing list:
> I tried to upgrade from 1.2.2 to 1.2.4 (and this problem occurred after every
> release after 1.2.2). Whenever I try to send a SOAP request to my service and
> it contains:
>
> <someNode></someNode> or <someNode />, I get a null pointer exception.
>
> If I put a line break in the node, or even a blank space, it works fine:
>
> <someNode>
> </someNode>
>
> The stack trace is below:
