Is This A Common Java Digital Signature Message?
<p>I'm a Java nub and I have a quick question about a Java Security Warning I had.</p>

<p>The warning window popped up and told me that the Digital Signature for something that was just named with about 15 random letters had expired.  I didn't see if there was a publisher but it may have been empty.  And the "From" field said "file://"</p>

<p>Is this normal activity or is there a potential security risk here?</p>

<p>Thanks all for any answers.</p>
