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
