   @Tibor17, I built M6 snapshot locally in your branch, then ran the tests on both branches of my simple [reproducer project](https://github.com/kriegaex/Maven_Surefire_PrintToConsoleProblems), which you already know. Findings:
   
   * `mvn clean test` passed now on branch _master_.
   * `mvn clean verify` still hangs on branch [_use-agent_](https://github.com/kriegaex/Maven_Surefire_PrintToConsoleProblems/tree/use-agent) after some output is written to the console. Probably something is still not 100% right. The log output:

   Please note that the initial `[Agent ERR]` line is missing and also all `[Transformer ERR]` ones. Did you maybe just fix stdOut, but not stdErr?
