RFR: 8202094: com/oracle/jfr/api/recording/event/TestEventTime.java intermittently times out

[Erik Gahlin]

Hi,

Could I have review of this test fix.

The helper function is supposed to wait for System.currentTimeMillis() 
to advance to a new value, but the check is incorrect, so it may instead 
end up in an infinite loop.

Thanks
