I removed a section of via JDK_JAVA_OPTIONS because including main class is not allowed in the specification. This behavior is added in JDK-8170832, which add JAVA_OPTIONS　environment variable. At this time, this test is mismatch with the specification. I tried to test and get Passed on Japanese Windows environment. Could you review this fix, please?
