Tibor Digana commented on SUREFIRE-1881:
----------------------------------------
It was observed from Windows 10.
I am using this line {{<forkNode
implementation="org.apache.maven.plugin.surefire.extensions.SurefireForkNodeFactory"/>}}
and I have observed exactly the same screen as you had (printed *T E S T S*
and then nothing). The dump file exists with the exception in it.
After the {{forkNode}} is deleted the test runs but strange and broken test
summary is printed which cannot be normally read. How this can be explained?

> Key: SUREFIRE-1881
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1881
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Failsafe Plugin, Maven Surefire Plugin
> Affects Versions: 3.0.0-M5
> Reporter: Alexander Kriegisch
> Priority: Major
>
> 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.
