The rpmbuild mock enviroment is like a sandbox, which created by `chroot` shell command, in the rpmbuild mock enviroment, `df -h` report `cannot read table of mounted file systems`, and java Files.getFileStore also throw `IOException`. We want to build and test the jdk in this `sandbox`, and the default jtreg work directory is `JTWork` in current directory, so this testcase will report fails.
