A DESCRIPTION OF THE PROBLEM :
test/hotspot/jtreg/gc/epsilon/TestMemoryMXBeans.java failed when running on linux.
According to the error message, it seems that the initial heap size is not set properly. JTR file shows -Xmx option appears twice in the second testcase.
Changing one of -Xmx option to -Xms option may make this test pass.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
STATUS:Passed.
ACTUAL -
