It looks good to me the change to clean up the build warnings.
On the other hand, not sure if we also should tweak this kind of method that it's passed deprecated systemProperties:

quarkus-test-framework/quarkus-test-core/src/main/java/io/quarkus/test/utils/MavenUtils.java

Line 74 in 483db30

public static List<String> devModeMavenCommand(ServiceContext serviceContext, List<String> systemProperties) {

@jcarranzan Please elaborate. System property is just named systemProperties, how does it relate to maven-failsafe-plugin configuration?

[jcarranzan]

My comment was just as a question, when I reviewed your PR I did a quick search of systemProperties and I found the same coincidence name that it's used on MavenUtils.java class so I just wanted to ensure that we are not overlooking any areas where deprecated systemProperties might cause warnings, but looking again as you mentioned the systemProperties in MavenUtils is unrelated to your changes.
Thanks.

Cool. So it's good to merge.
