According to my investigation, this issue was happened after following change was applied.
JDK-8272600: (test) Use native "sleep" in Basic.java

test.nativepath value was added into AIX's LIBPATH during running this testcase.
On AIX, test.nativepath value should be removed from LIBPATH value before comparing the values.
