-------------------------------------------------------
Can someone let me know if my below understanding is correct or not after
reading the documentation:-
All the classes marked with {{@NotThreadSafe}} runs in a single thread one
after another. This single thread executing {{@NotThreadSafe}} test classes
runs after all the threads executing tests in parallel are finished.
was (Author: tuk):
What is the behavior are the classes marked with @NotThreadSafe running in a
single thread after the all the parallel executions are finished?

> Key: SUREFIRE-1373
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1373
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Plugin
> Affects Versions: 2.20
> Reporter: Sebastian Kirsch
> Assignee: Tibor Digana
> Fix For: 2.20.1
>
>
> The [surefire
> documentation|http://maven.apache.org/components/surefire/maven-failsafe-plugin/examples/fork-options-and-parallel-execution.html]
> states that
> bq. you can apply the JCIP annotation @net.jcip.annotations.NotThreadSafe on
> the Java class of JUnit test (pure test class, Suite, Parameterized, etc.) in
> order to execute it in single Thread instance. The Thread has name
> maven-surefire-plugin@NotThreadSafe and it is executed at the end of the test
> run.
> However, the thread is run in parallel to the other tests being executed,
> which contradicts the documentation and defeats the purpose of running tests
> sequentially in a single thread.
> See https://github.com/sebastiankirsch/surefire-nonthreadsafe for a test case.
