[Tristan Yan]

Hi All

Please help to review a simple fix for https://bugs.openjdk.java.net/browse/JDK-8030844

http://cr.openjdk.java.net/~tyan/JDK-8030844/webrev.00/.

Description:
Change replace a “/home/~user" folder with an test source path. Folder “/home/~user” cause some problem whenever something wrong with the automount filesystem or an username lookup problem. 

Thank you
Tristan
