Emma  report merging achieved by renaming coverage.ec file after graceful
server restart, and providing all *.ec files when creating reports.

Emma doesn't provide a way to generate unique .ec file when jvm exists.
Actually it uses same name and overwrite the file at specified location.
AFAIU there's no way to change default behavior.

Thanks,
Krishantha.
