------------------------------------------------

Thank you [~robertlazarski]. I am very tempted to move onto Axis2 but unfortunately \
am stuck with a legacy application that is too resistant to change.

> Reason:
> org.apache.axis.configuration.FileProvider.configureEngine(AxisEngine) uses \
> getInputStream() and setInputStream() methods to load the client config wsdd. These \
> getter and setter methods read or modify the 'myInputStream' class member variable \
> and is not thread-safe 
> Fix:
> Use a local  InputStream method local variable to load the client config file. The \
> stream is loaded and consumed in this method, so a local variable is appropriate \
> here. Please find attached the unified diff file with the proposed fix.
