package edu.umd.cs.findbugs;

import java.io.IOException;

import edu.umd.cs.findbugs.classfile.IClassPath;

Signals that FindBugs found no classes on the classpath it was invoked to
analyze.
 To be consistent with FindBugs 1.3 this exception is an IOException and replicates the message used in that release (because I suspect some tools looked for that text pattern to come out at the console).
