Using wsimport to compile a WSDL with multiple <message> stanzas that have
<part> elements with non-unique "name" attributes, the operation fails with
'[ERROR] Failed to generate Java signature: duplicate parameter name "param".
Try one of these
1. Use JAXWS binding customization to rename the wsdl:part "param"
2. Run wsimport with -extension switch.'
Using a customization file as per item 1. and/or using the -extension switch
as per item 2. does not address the issue, and the same error is encountered.
