title: Provider not found exception when creating a FileSystem for my zip?
body: <p>I have created a Zip file on a JimFS <code>FileSystem</code> instance. I would now like to read the Zip using the Java <code>FileSystem</code> API. </p>
  
  <p>Here is how I create the <code>FileSystem</code>:</p>
  
  <pre><code>final FileSystem zipFs = FileSystems.newFileSystem(
      source, // source is a Path tied to my JimFS FileSystem
      null);
  </code></pre>
  
  <p>However, this throws an error: </p>
  
  <blockquote>
    <p>java.nio.file.ProviderNotFoundException: Provider not found</p>
  </blockquote>
  
  <p>Interestingly, the code works with the default <code>FileSystem</code>. </p>
