CommandLineUtils is used in Maven-Surefire to start forks which execute tests. It is a well known issue that sometimes child processes are not killed correctly. This is a known limitation of JVM, and the only reliable way to implement it would be platform specific.
Bug report in Surefire JIRA:
JVM bug report. It's Windows specific, but the problem exists on Linux and OSX as well.
I'm proposing either 1) to implement several platform specific implementations of ProcessHook or 2) to make the mechanism of killing processes extendable for clients of the library.
