How to resolve a "Null manifest from input stream associated with" warning
<p>I'm trying to stop the warning: </p>

<pre><code>JarClassLoader: Warning: Null manifest from input stream associated with: &lt;path to lib / jar file&gt;
</code></pre>

<p>which gets displayed every time I run my java application. I realise that it doesn't stop it working, but I assume a warning is there for a reason and I'd like to understand why and how.</p>

<p>For reference, the jar file is being created using one-jar.
I've looked at this <a href="http://stackoverflow.com/questions/3662659/one-jar-remove-verbose-warning-information-on-application-load">stackoverflow question/answer</a> but this seems to be more about suppressing messages rather than resolving them. </p>

<p>It also has been asked <a href="http://sourceforge.net/tracker/index.php?func=detail&amp;aid=3139182&amp;group_id=111153&amp;atid=658458" rel="nofollow">here</a> but again I couldn't find an answer.</p>
