DumpExecutionDataTest should not forcibly terminate Java processes (e…

…clipse-eclemma#38)

Forced termination sometimes causes the appearance of the dialog
"No Coverage Data"

> No coverage data has been collected during this coverage session.
> Please do not terminate the Java process manually from Eclipse.

leading to the failure of subsequent tests
