Because of garbage in string variables and occasional IndexOutOfBoundsException
/ ConcurrentModificationException
in logs it seems like a concurrency issue.
This GitHub issue - [#6254] Maven-failsafe-plugin fails to execute integration tests - and the related discussion helped me to solve my problem.
It's a bug. It turns out that newer Failsafe plugin versions (2.19.0 and later) don't work well with Spring Boot 1.4 (or later). Workaround is to downgrade the maven-failsafe-plugin to 2.18.1. Here's the updated pom.xml:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<!-- I don't specify version at all (Spring Boot can autoconfigure plugin version) -->
<executions>
<execution>
<!-- changed <id> to <phase>, but I don't know whether it's important or not. -->
<phase>integration-test</phase>
<!-- ... no changes here: the same as in the question ... -->
</execution>
</executions>
</plugin>
</plugins>
