To reproduce Using the https://github.com/openliberty/guide-maven-multimodules project

1. Start dev mode mvn liberty:dev -DhotTests with 3.6-SNAPSHOT of Liberty Maven Plugin
2. Make a java file change to the /war directory, notice that the tests run for the jar, war and ear modules:

Expected behaviour Since the java file change was in the war directory, only the tests for the war and ear directories should run (changed module and dependent modules). With3.5.2:
