title: Why are we getting ClosedByInterruptException from FileChannel.map in Java 1.6?
body: <p>A customer of ours complains that, sporadically, calls of ours to <code>FileChannel.map</code> fail with a <code>ClosedByInterruptException</code>. The <a href="http://java.sun.com/javase/6/docs/api/java/nio/channels/FileChannel.html#map(java.nio.channels.FileChannel.MapMode,%20long,%20long)" rel="noreferrer">Javadoc</a> does not list this as a legitimate possibility. Does anyone know what might be going on here?</p>
