Bernd Fondermann closed VYSPER-252.
-----------------------------------
> Not well formed XML does not terminate XMPP stream
> --------------------------------------------------
>
> Key: VYSPER-252
> URL: https://issues.apache.org/jira/browse/VYSPER-252
> Project: VYSPER
> Issue Type: Bug
> Components: core protocol
> Affects Versions: 0.6
> Reporter: Bernd Fondermann
> Priority: Critical
>
> When the server receives a stanza which contains not well-formed (NWF) XML,
> the XMPP stream must be closed immediately.
> Vysper detects, but currently doesn't close on NWF XML:
> <item> miltjackson Map<String, String> zappa </item>
> DefaultNonBlockingXMLReader returns FatalError, but the XMPP stream isn't
> closed.
> (I tried to set up a case, but didn't find any boilerplate code).
> Subsequently, "org.apache.mina.filter.codec.ProtocolDecoderException:
> org.xml.sax.SAXException: Parser is closed" is thrown.
