> In test class TestDiskChecker, test case will fail if tmp dir's usableSpace / totalSpace > 0.95, because threshold will be a negative number.
> {code}
> public void testCheckDiskFull() throws IOException {
> File file = File.createTempFile("DiskCheck", "test");
> long usableSpace = file.getUsableSpace();
> long totalSpace = file.getTotalSpace();
> float threshold =
> (1f - ((float) usableSpace / (float) totalSpace)) - 0.05f;
> < === if "usableSpace / totalSpace" is 0.99, then threshold is -0.04, this is invalid.
> diskChecker.setDiskSpaceThreshold(threshold, threshold);
> diskChecker.checkDiskFull(file);
