Cause
Cause type:
Defect
Root Cause: RA WebService Agent v3 uses Axis2 framework which causes the problem.
Defect
Root Cause: RA WebService Agent v3 uses Axis2 framework which causes the problem.
Environment
OS Version: N/A
Resolution
Update to a fix version listed below or a newer version if available.
The issue is fixed with RA Webservice Agent Solution Soap v4.1 which is compatible with Automation Engine 12.
There won't be a fix for RA Web Service Agent v3 because the RA Web Service Agent v3 uses Axis2 framework that causes the problem.
For obvious reasons we can not change the framework for a released major version as this would bring in incompatiblity changes and therefore conflict with our release policy.
The RA SOAP Web Service Solution v4.1 Agent is not dependent upon any framework because it uses a native mode therefore the issue can't be reproduced with this Agent version.
Fix Status: Released
Fix Version(s):
RA WebServiceSolution SOAP 4.1 - Available
