> Hi all,
> 
> Before this PR, if the jtreg work directory and the /tmp directory locate in different linux volume or disk partition, test will report fails "java.nio.file.AtomicMoveNotSupportedException: file -> file: Invalid cross-device link". The linux syscall `rename()` doesn't support rename file across different volume, so I think the AtomicMoveNotSupportedException is not a JVM bug.
> 
> This PR try to catch the AtomicMoveNotSupportedException and throw a SkippedException rather report fails. And split this test as two tests, one test for the default temporary directory '/tmp', another test for current jtreg work directory, this will make sure at least one test run non-skipped.

SendaoYan has updated the pull request incrementally with one additional commit since the last revision:

  Add @buildjtreg.SkippedException before @run
