Failsafe Integration tests don't suspend with debug profile

Question

I've got a java 11 application that runs my spring-boot based webserver in the maven pre-integration phase test then runs integration tests during the integration test phase via failsafe.

I'm trying to connect a remote debugger to the running tests to track down an issue.

The problem I'm running into is that my maven profile that sets the debug args will cause the server that is started in pre-integration-test to listen for a debugger but failsafe does not suspend as instructed when I activate the profile.

I have the maven.failsafe.debug property set via the profile as instructed on the failsafe docs: https://maven.apache.org/surefire/maven-failsafe-plugin/examples/debugging.html

    <profile>
        <id>debug-it</id>
        <properties>
            <it.debugArgs>-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:40000</it.debugArgs>
            <maven.failsafe.debug>-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:40001 -Xnoagent -Djava.compiler=NONE</maven.failsafe.debug>
        </properties>
    </profile>

I've updated maven to 3.8.5 and failsafe to the latest, 3.0.0-M6. A similar profile used to work before migrating my service from java 8 to java 11 a year or so ago.

Note I've also tried manually setting the failsafe debug option directly on the terminal with the same result.

Any idea what I'm doing wrong?
