[jira] [Commented] (AXIS2-5473) System hangs (cpu 100%) after
sending a corrupt soap message
[ https://issues.apache.org/jira/browse/AXIS2-5473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13565277#comment-13565277 ]
Mario Hercog commented on AXIS2-5473:
-------------------------------------
Problem is in the adb (default databinding method) generated part of the code.
public static <Type> parse(javax.xml.stream.XMLStreamReader reader) method generates the following endless loop:
while(!reader.isEndElement()) {
if (reader.isStartElement() ){
if (reader.isStartElement() && new javax.xml.namespace.QName("URI","choice1").equals(reader.getName())){
reader.next();
} // End of if for expected property start element
else if (reader.isStartElement() && new javax.xml.namespace.QName("URI","choice2").equals(reader.getName())){
reader.next();
} // End of if for expected property start element
} else {
reader.next();
}
} // end of while loop

> Key: AXIS2-5473
> URL: https://issues.apache.org/jira/browse/AXIS2-5473
> Project: Axis2
> Issue Type: Bug
> Affects Versions: 1.6.1, 1.6.2
> Environment: Tomcat 7.0.6
> Java 6.0.27
> Windows 7 (and unix too)
> Reporter: Robert van Dijk
> Priority: Critical
> Attachments: SomeServiceHANG.aar, SomeService.wsdl
>
>
> If I sent (using soapui) an invalid soap message, the cpu usage goes up to 100%. There's no response. After stopping the webserver, the cpu usage goes back to normal.
>
> There are some choice fields and an optional field in the request. If I mess up one specific closing tag (example: see corrupt soap message below), the problem occurs.
> It's easy to "trigger" this problem.
> - Generate code from wsdl
> - Produce an aar file (no skeleton implementation needed)
> - Deploy the aar (for example locally on your PC)
> - Use soapui for the invalid soap message
> - Windows task manager shows the performance
> Corrupt soap message
