----------------------------------------------
Oops, sorry. Certainly right.
> InternalError when parsing invalid XML
> --------------------------------------

> Key: XERCESJ-1491
> URL: https://issues.apache.org/jira/browse/XERCESJ-1491
> Project: Xerces2-J
> Issue Type: Bug
> Affects Versions: 2.9.1
> Environment: XercesJ 2.9.1, JDK6, at least on Linux and Solaris
> Reporter: Volker Kleinschmidt
>
> We're getting java.lang.InternalError from scanDocument() instead of some
> sensible exception when trying to parse XML that contains unclosed tags -
> this should be handled more gracefully.

> Note how the <handle>, <create> and <remove> tags are not terminated, i.e it
> should read <create .... />.
> Clearly the document fragment is invalid XML, but that shouldn't cause an
> InternalError under any circumstance!
> Example of a malformatted document fragment triggering this behavior:

> <!-- Custom content types defined by this extension -->
> <content-handlers>
> <content-handler>
> <name value="Document Package" />
> <handle value="resource/x-jjc-docset">
> <http-actions>
> <create value="modules/create.jsp">
> <remove value="modules/remove.jsp">
> </http-actions>
