While migrating a rather old and big project from Java 8 to Java 11 the
following exception happens occasionally (once in 3-4 builds):
{code:java}

The tests run on Jenkins ver. 2.204.6 like this:
{code:java}
realtimeJUnit('**/target/surefire-reports/*.xml') {
sh "mvn test -e -T 1C"
}
{code}
{code:java}
mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/apache-maven-3.6.3
Java version: 11.0.8, vendor: Amazon.com Inc., runtime:
/usr/lib/jvm/java-11-amazon-corretto
{code}
With exactly the same setup but using Java 8 this exception doesn't occur.
Also, with the plugin version 2.22.2 there is no exception but also
occasionally some random tests fail with
{code:java}
java.lang.NoClassDefFoundError:
....
Caused by: java.lang.ClassNotFoundException:
{code}
even thought classes are located right next to each other (sometimes it even
fails to find inner static class)
