SOAP Web Service AFX test connector capabilities fail with 'Failed to create service' and 'Unexpected EOF in prolog' messages in RSA Identity Governance & Lifecycle

RSA Product Set:  Identity Governance & Lifecycle 
RSA Version/Condition:  6.9.1, 7.0.x, 7.1.x
 

When testing SOAP Web Service AFX connector capabilities (AFX > Connectors > {connector-name} > Test Connector Capabilities)  the following error message displays in the user interface:
  Looking at the file with a name similar to $AFX_HOME/esb/logs/esb.AFX_CONN_{connector-name}_test.log, you first see:
     

The WSDL file being referenced works as expected when accessed from the SoapUI.

The significant error message here is the last error message:
 
This error indicates that there is a parsing issue in the WSDL file being accessed.

When pulling up the WSDL file in Notepad++ or a similar editor, you can see that the lines are terminated by CRLF. This indicates that the WSDL file might have been created on Windows, and the Linux Operating System does not necessarily interpret this character correctly. SoapUI tends to be more forgiving and has no issue with the CRLF character.

The solution involves two steps:

1. Edit the WSDL file and remove the CRLF characters at the end of the lines. An example is provided below:

2. Convert the file to Unix format. For example, if you are using Notepad++, select Edit > EOL Conversion > UNIX/OSX Format. 

3. Save the file using File > Save.
