Alexander Kriegisch commented on SUREFIRE-1881:
-----------------------------------------------
[~tibordigana], how long ago did you clone the repository? In the current
master which I pushed 14 hours ago there is no Java agent anymore. You must
have used an older version and for the 5th time not done what I told you to: to
deactivate the agent in order to focus on the problem which is certainly *not*
caused by the agent. Is it like my words are non-existent for you? Did you put
my posts on a spam filter or so? I cannot believe you are still doing the same
as before, even after I told you so many times that you do not need any agents
in order to reproduce this problem. Your log output proves that you use the
agent, chasing ghosts instead of focusing on the actual problem. Maybe you fix
that one first. Then afterwards, if it works without the agent but then another
problem still persists when switching back to the agent on the other repository
branch, we can focus on that one. Why not start simple and do the more complex
stuff afterwards?

> This is a follow-up to SUREFIRE-1788 which was closed prematurely even though
> there still were open issues which were discussed there initially. Basically
> the situation is as follows:
> * I use Java agents writing to stdOut and stdErr in my tests.
> * I was annoyed that Surefire/Failsafe were writing lots of {{[WARNING]
> Corrupted STDOUT by directly writing to native stream in forked JVM}} lines
> into {{*-jvmRun1.dumpstream}} files. [~tibordigana] then told me to use
> {{<forkNode
> implementation="org.apache.maven.plugin.surefire.extensions.SurefireForkNodeFactory"/>}}
> in my POM in order to fix the issue.
> * I tried this in version 3.0.0-M5, but unfortunately, it makes
> Surefire/Failsafe freeze if a Java agent prints something to stdOut or
> stdErr. This happens both in M5 and in M6-SNAPSHOT after both SUREFIRE-1788
> and SUREFIRE-1809 have been merged in already.
> * My [sample
> project|https://github.com/kriegaex/Maven_Surefire_PrintToConsoleProblems]
> reproduces the issue as soon as you uncomment the option in the POM and run
> {{mvn clean verify}}.
> * The second issue is: *Not* using this option leads to garbled log output
> when a Java agent writes to both stdOut and stdErr before/during tests. See
> comments in class
> [{{Agent.DummyTransformer}}|https://github.com/kriegaex/Maven_Surefire_PrintToConsoleProblems/blob/master/src/main/java/de/scrum_master/dummy/Agent.java]
> for examples for garbled log lines and also comments in
> [pom.xml|https://github.com/kriegaex/Maven_Surefire_PrintToConsoleProblems/blob/master/pom.xml#L36]
> for further information.
> * If the garbled output would also appear with this option activated, cannot
> be tested at present due to the Surefire/Failsafe freeze. I will re-test that
> after the freeze has been fixed and before this issue can be closed.
