8269418: jdk/jfr/event/oldobject/TestObjectSize.java failed with "RuntimeException: No events: expected false, was true"

[mgronlun]

Greetings,

please help review these adjustments to make the test more robust, i.e. neither trap on an invalid assertion nor timeout because of too many retries.

Testing: jdk_jfr (300 times)

Thanks
Markus
