Subject [jira] Resolved: (CLEREZZA-314) SAXException in platform.typerendering
Date Mon, 04 Oct 2010 17:08:34 GMT

     [ https://issues.apache.org/jira/browse/CLEREZZA-314?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Manuel Innerhofer resolved CLEREZZA-314.
----------------------------------------

    Resolution: Fixed

According to http://lists.owldl.com/pipermail/pellet-users/2007-August/001756.html the exception
is caused by multiple threads calling concurrently the parse method of a DocumentBuilder.
As solution I synchronized the parse call in GenericGraphNodeMBW .
