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? {noformat} [INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.378 s - in de.scrum_master.dummy.AgentIT [Transformer OUT] className = org/junit/runner/notification/RunNotifier$2, loader = jdk.internal.loader.ClassLoaders$AppClassLoader@6ff3c5b5 [Transformer ERR] className = org/junit/runner/notification/RunNotifier$2, class file size = 1131 [Transformer OUT] className = org/apache/maven/surefire/api/suite/RunResult, loader = jdk.internal.loader.ClassLoaders$AppClassLoader@6ff3c5b5 [Transformer ERR] className = org/apache/maven/surefire/api/suite/RunResult, class file size = 5263 [Transformer OUT] className = org/apache/maven/surefire/booter/ForkedBooter$6, loader = jdk.internal.loader.ClassLoaders$AppClassLoader@6ff3c5b5 [Transformer ERR] className = org/apache/maven/surefire/booter/ForkedBooter$6, class file size = 1036 [Transformer OUT] className = org/apache/maven/surefire/booter/ForkedBooter$7, loader = jdk.internal.loader.ClassLoaders$AppClassLoader@6ff3c5b5 [Transformer ERR] className = org/apache/maven/surefire/booter/ForkedBooter$7, class file size = 1564 [Transformer OUT] className = java/util/concurrent/ScheduledThreadPoolExecutor$ScheduledFutureTask, loader = null Transformer ERR] className = java/util/concurrent/ScheduledThreadPoolExecutor$ScheduledFutureTask, class file size =[ 4I3NF3O8] [INFO] Results: [Transformer OUT] className = java/util/concurrent/FutureTask, loader = null m[TrINaFnOsf]o r ir[ ERIRN]F Ocl]a ssNTaemset s= rjuanv:a /1u,t iFla/iclounrceusr:r e0n,t /EFrurtourrse:T a0s,k ,S kcilpapseds: 0 f [eI NsFiOze] = 9022 [WARNING] Corrupted STDOUT by directly writing to native stream in forked JVM 1.

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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
