[jdk20] RFR: 8298455: JFR: Add logging to TestClose.java

[Erik Gahlin]

Hi,

Could I have a review of a test fix. 

The test jdk/jfr/api/consumer/recordingstream/TestClose.java times out intermittently, but the thread dump looks fine. One possibility is that the onEvent action is never registered. It would be good to verify that the registration mechanism works properly. This can be done by logging with -Xlog:jfr+streaming+system=trace

Testing: running test locally

Thanks
Erik
