No.

Enable debug logging for HTTP/2 (see logging.properties), run the simplest test 
that exhibits the problem and review the logs.

If the issue isn't clear from reviewing the logs, put the log file somewhere we 
can download it and someone will take a look.

Is there any particular issue with HTTP/2 ?
