Problem: For Web service and other data sources with very complex structures with deeply nested element trees, StackOverflow or OutOfMemory may occur, or some of the operation input parameters may not be generated properly.
Explanation: When a WSDL or other complex data source is wsdl is deeply nested, long processing times and memory errors can result.
Solution: Increase the stack and heap size of the Eclipse runtime parameter in UnwiredWorkSpace.bat with -Xmx, -Xms, -Xss arguments, or reduce the complexity or nested level of the Web service definition of the MBO operation.
