Subject [jira] [Created] (AXIS2-5473) System hangs (cpu 100%) after sending a corrupt soap message

Robert van Dijk created AXIS2-5473:
--------------------------------------

             Summary: System hangs (cpu 100%) after sending a corrupt soap message
                 Key: AXIS2-5473
                 URL: https://issues.apache.org/jira/browse/AXIS2-5473
             Project: Axis2
          Issue Type: Bug
    Affects Versions: 1.6.2, 1.6.1
         Environment: Tomcat 7.0.6
Java 6.0.27
Windows 7 (and unix too)
            Reporter: Robert van Dijk
            Priority: Critical


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
