The error comes from junit - we are outputting too much stuff to stdout/stderr!

{code}
443 systemError.close();
444 systemError = null;
445 systemOut.close();
446 systemOut = null;
447 if (startTestSuiteSuccess) {
448 sendOutAndErr(new String(outStrm.toByteArray()),
449 new String(errStrm.toByteArray()));

{code}
I will fix it together with this patch.
