File.createNewFile() randomly fails

Question

I\'ve build a simple test which creates and deletes a file (name does not change) in an infinite loop. The test does run for a couple of seconds (sometimes over 77,000 iteration

Try this:

final File f = new File("file");
    while (true) {
        final boolean create = f.createNewFile();
        if (!create) {
            System.out.println("crate failed");
        } else {
            final boolean delete = f.delete();
            try {
                Thread.sleep(10);
            } catch (InterruptedException e) {
                System.out.println("...");
            }
            if (!delete) {
                System.out.println("delete failed");
            }
        }
    }

In this way we ensure that the file is released by the delete before invoking createNewFile.
