> Tomcat using 100% CPU when application/json (JSONMessageFormatter) is used
> --------------------------------------------------------------------------
>
> Key: AXIS2-5440
> URL: https://issues.apache.org/jira/browse/AXIS2-5440
> Project: Axis2
> Issue Type: Bug
> Affects Versions: 1.6.0, 1.6.2
> Environment: Apache Tomcat/6.0.35 1.6.0_21-b07 Sun
> Microsystems Inc. Windows 7 6.1 x86
> Reporter: Ladislav Lencucha
> Labels: JSON
> Attachments: axis2.xml, ConsoleServer.aar, ws.zip
>
>
> I am trying to connect to my webservice using GET + JSON.
> I've added JSONMessageFormatter and JSONOMBuilder for "application/json"
> content type.
> When I try to call the webservice using jQuery and HTTP GET with content type
> "application/xml" I receive the response almost immediately (note that there
> is a jQuery error raised afterwards, because Xml cannot be parsed as JSON).
> When I try to call the webservice using the same code but with content type
> "application/json" there is no response and Tomcat uses 100% of CPU (there
> are also some messages in log file mentioning that it should have ended).
> See my aar file and jQuery example attached. Also see my axis2.xml
> configuration.
