java/lang/ClassLoader/platformClassLoader/DefinePlatformClass.java 8169639 windows-all

It's clear now that the failure is caused by machine wrong time setting.

As mentioned in JDK-8169639, "Like other frameworks which use relative to decide which dependencies need to be rebuilt, jtreg will not do what is wanted if the machine time is in the future compared to file timestamps."

From the test failure log, jtreg failed at compiling action with: "has a modification time in the future ... Unexpected results may occur" and it's confirmed that the machine in question has wrong time setting.
