RFR(S): 8146096: [TEST BUG] compiler/loopopts/UseCountedLoopSafepoints.java Timeouts

[Andreas Eriksson]

Hi,

Can I please have a review for the removal of 
hotspot/test/compiler/loopopts/UseCountedLoopSafepoints.java.

The test needs to do a loop that takes more than two seconds to execute 
fully without doing a safepointing call. For this expensive atomic 
operations were used. The problem is that on certain embedded platforms 
they are too expensive, and the test times out.
The loop length could probably be reduced, and it should still work on 
faster machines. However, the test is not very useful, so I think it's 
better to just remove it to avoid future problems.

Bug: https://bugs.openjdk.java.net/browse/JDK-8146096
Test to be removed: 
http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/file/d84a55e7aaf8/test/compiler/loopopts/UseCountedLoopSafepoints.java
(I can create a webrev if you think it necessary.)

Thanks,
Andreas
