Hi, Please help the small update to the test case tools/jar/ChangeDir.java, which might fail if the "dedicated" test directory /tmp/a exists and the user does not have privilege to delete/clean it up.
The proposed change here is to use a random file name (from File.getTempFile()) for the top test directory (instead of the fixed /tmp/a), and really clean it up after testing (the old test leaves /tmp/a and those temp files undeleted). http://cr.openjdk.java.net/~sherman/8023113/webrev Thanks, -Sherman
