      Description

        $ CONF=linux-x86-server-fastdebug make run-test TEST=jdk/jfr/event/allocation/TestObjectAllocationInNewTLABEvent.java

        STDOUT:
        STDERR:
        java.lang.RuntimeException: Too few tlab objects allocated: expected 50 >= 80
        at jdk.test.lib.Asserts.fail(Asserts.java:594)
        at jdk.test.lib.Asserts.assertGreaterThanOrEqual(Asserts.java:288)

        I think the test makes questionably assumptions about the size of byte array allocated, which fail on 32-bit platforms.
