What does the test verify? When I run the test on a build that does not 
have your fix it still passes:

$ java -showversion -jar /localhome/tests/jtreg/lib/jtreg.jar -noreport 
test/gc/TestScavengeALot.java
java version "1.9.0-ea"
Java(TM) SE Runtime Environment (build 1.9.0-ea-b35)
Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b35, mixed mode)

Test results: passed: 1


Also, since this is a CMS specific test I think it should be located in 
the "test/gc/concurrentMarkSweep".
