After a bit of thinking about it, my guess is that the svn server only
accepts unlimited lock timeouts (which was always the case with XXE
v4+). That is, it's simply a minor, may be documented, limitation of the
svn implementation of WebDAV.

PS: The .jnlp file allows you to pass options to XXE. See
application-desc/argument:
<application-desc main-class="com.xmlmind.xmleditapp.start.WebStart">
<argument>-putpref</argument>
<argument>lockTimeout</argument>
<argument>0</argument>
</application-desc>
There is no harm nor penalty in forcing this user preference each time
XXE is started.
