RFR: 8067368: TestConcMarkCycleWB.java crashed at G1CollectedHeap::heap()+0xb

[Stefan Johansson]

Hi,

Please review this small fix to add TestConcMarkCycleWB.java to the 
needs_g1gc test group. This should fix the nightly problem described in:
https://bugs.openjdk.java.net/browse/JDK-8067368

Webrev:
http://cr.openjdk.java.net/~sjohanss/8067368/hotspot.00/

Summary:
The runs failing this test are executed with either the test-group 
"embedded_jdk" or "embedded_jre". Both those exclude tests defined in 
the group "needs_g1gc" and since TestConcMarkCycleWB.java is a G1 
specific WhiteBox test it should be included in the "needs_g1gc" group.

Test:
Manually verified that a jtreg of execution for "embedded_jdk" or 
"embedded_jre" after the patch is applied don't include 
TestConcMarkCycleWB.java.

Thanks,
Stefan
