Description

The fix should be relatively simple, just add an identity check to the beginning of the method:

if(is1 == is2) {
return true;
}

The methods affected are:

• org.apache.commons.io.IOUtils.contentEquals(InputStream, InputStream)
• org.apache.commons.io.IOUtils.contentEquals(Reader, Reader)
• org.apache.commons.io.IOUtils.contentEqualsIgnoreEOL(Reader, Reader)
