[Alexander Kulyakhtin]

Hi,

Could you, please, review this quarantine request:

CR: https://bugs.openjdk.java.net/browse/JDK-8147848 "https://bugs.openjdk.java.net/browse/JDK-8147848"
Webrev: http://cr.openjdk.java.net/~akulyakh/8147848/index.html

The 3 tests need to be quarantined until the root cause of the failures found.

Best regards,
Alexander
