RFR: 8067751: OOMEInReferenceHandler.java fails: Cleaner terminated abnormally

[Michail Chernov]

Hi,

Please review small change for OOMEInReferenceHandler.java test.

Webrev: http://cr.openjdk.java.net/~eistepan/~mchernov/8067751/webrev.00/
Bug: https://bugs.openjdk.java.net/browse/JDK-8067751

Root cause: test fails due to OOME ("GC overhead limit exceeded ") is 
occurred.
Suggested fix : run test with -XX:-UseGCOverheadLimit to disable OOME 
(which is occurred because of excessive GC overhead).

Thanks,
Michail
