Subject [jira] [Comment Edited] (SUREFIRE-1193) Surefire 2.19 hangs in the log4j build

Why the Jenkins build crashed after hanging? It really hanged for some time so that the CPU
was very low?
Who did shutdown the forked JVM?

Can you just print test class name in @BeforeClass?
We need to see which class is in the middle.

There's one situation when the JVM may shutdown itself. The plugin JVM sends commands to forked
JVM. The Forked JVM receives the command in std/in. If the std/in stream is corrupted so that
the command cannot be decoded, the reader throws an exception which may result shutdown. We
should find out if this is happening. If it is this case then the question is why Maven process
would corrupt the stream.

> Log4j is getting periodic failures in Jenkins with the messages shown below. I am also
seeing running the tests hang in various log4j modules when building on my MacBook Pro. The
build never hung when using 2.18. We have reverted back to surefire 2.18 due to this.
> The full build output is temporarily available at https://builds.apache.org/job/Log4j%202.x/1520/console.
We only keep the last 15 builds.
