When trying to build logback on Ubuntu 10.04, the test unknownURL in ch.qos.logback.core.joran.action.IncludeActionTest fails.

The test is currently looking for either a UnknownHostException or IOException to be raised. In practice, on the stated environment, the following exceptions are raised;

19:04:20,488 |-ERROR in ch.qos.logback.core.joran.event.SaxEventRecorder@1016632 - XML_PARSING - Parsing fatal error on line 6 and column 113 org.xml.sax.SAXParseException: The reference to entity "ClientLocation" must end with the ';' delimiter.
at org.xml.sax.SAXParseException: The reference to entity "ClientLocation" must end with the ';' delimiter.
...

19:04:20,488 |-ERROR in ch.qos.logback.core.joran.action.IncludeAction - Error while parsing http://logback2345.qos.ch ch.qos.logback.core.joran.spi.JoranException: Problem parsing XML document. See previously reported errors.
at ch.qos.logback.core.joran.spi.JoranException: Problem parsing XML document. See previously reported errors.

The simplest solution would to add the SAXParseException to the list of acceptable exceptions, but wonder if that's masking a wider problem ...
