        Description

        This test is failing after hs-rt is merged with jdk9/hs, which means we can't sync down jdk9/hs to hs-rt. The test fails every time, only on Solaris x64.

        Verifying memory usage in space: TENURED
        Allocated objects count: 655360
        Desired object size: 16
        Actual object size: 16
        Expected object size in space: 16
        Expected memory usage: 14026192
        Actual memory usage: 13075920
        Memory usage diff: 950272
        Max allowed usage diff: 701312
        STDERR:
        java.lang.RuntimeException: Actual memory usage should not deviate from expected for more then 701312 (assert failed: 950272 <= 701312)
