Hi Daniil,

Could you, please, replace 'e' with 'event'?
I've never liked one-letter identifiers.
Other than that it looks good to me.

Thanks,
Serguei

The test also uses breakpoints to synchronize with the debuggee,  but the problem here is that while waiting for a breakpoint event, occasionally, when Graal is on, the event the test receives is a ThreadStartEvent for " HotSpotGraalManagement Bean Registration" thread, rather than a breakpoint event. The test doesn't expect it and fails.
