I'm not sure I understand what you are saying.

`redirectErrorStream`: Tells whether this process builder merges standard error and standard output.

So all I'm doing is merging the stdout and stderr from the process. Now everything from the process goes to the stdout of the process, right? Then I can check `output.equals("")` and that captures that there is neither any thing on the stdout nor on the stderr of the process.

Nothing is actually being printed in the JTREG stdout. Correct?
