The `df -h` command return fail `df: cannot read table of mounted file systems: No such file or directory` on the rpm build mock environment also. I think it's a environmental issue, and the environmental issue should not cause the test fails, it should skip the test.

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.

We have had several enhancement reports (in jtreg) for better reporting skipped tests. Some relate to what the make scripts in the JDK report and some from jtreg reports themselves. I'll have to go back and check if the one you note about is something that we are already aware about. For now though, your change to use `SkippedException` looks correct to me.
