Hello, At Apache Wicket we hit issue described here https://stackoverflow.com/a/53016532/1676516 (tests fails when OpenJDK 8u181 is used)
To fix it we have tried to update maven-surefire-plugin (2.20 -> 3.0.0-M1) Tests for one module (CDI-1.1) fails for both OpenJDK and OracleJDK I tried to fix these tests - no luck Then I have added <useSystemClassLoader>false</useSystemClassLoader> to surefire-plugin configuration and tests become green So I guess this should be maven-surefire-plugin issue The issue can be checked using Apache Wicket sources available here https://github.com/apache/wicket/tree/wicket-8.x (please NOTE `wicket-8.x` branch) Please let me know if any additional details are required -- WBR Maxim aka solomax
