Local recordings work fine:

    try (RecordingStream stream = new RecordingStream()) {
      stream.enable("jdk.CPULoad").withPeriod(ofSeconds(1));
      setEventHandlerAndStartAsyncRecording(stream);
    }

Recording.RecordingSettings append the prefix

RemoteRecording works only when the key is constructed manually:

    try (var stream = new RemoteRecordingStream(mBeanServerConnection)) {
      stream.enable("jdk.CPULoad").with("jdk.CPULoad" + "#period", "1000ms");
      setEventHandlerAndStartAsyncRecording(stream);
    }

Otherwise things like .withPeriod() don't work.

with() doesn't do prefixing

but enable()/disable() perform some prefixing to call with():
