This seems OK.

Note that container tests are pretty verbose when it comes to test output. Usually stderr/stdout get capped by jtreg and sent to a file instead. IIUC the use case would be to get hs_err.log files to stderr in case of crashes. However, if the stderr value gets truncated, then you'd be back at square one.
