> The testProperties.execCmd() is used to fork a JVM and not handle its
> streams. This will cause problems, as indicated by the javadoc for Process.
> "The parent process uses these streams to feed input to and get output
> from the subprocess. Because some native platforms only provide limited
> buffer size for standard input and output streams, failure to promptly
> write the input stream or read the output stream of the subprocess may
> cause the subprocess to block, and even deadlock"
