Call to 'equals()' or 'hashCode()' on 'URL' object

Reports hashCode() and equals() calls on objects and calls that add URL objects to maps and sets.

URL's equals() and hashCode() methods can perform a DNS lookup to resolve the host name. This may cause significant delays, depending on the availability and speed of the network and the DNS server. Using instead of will avoid the DNS lookup.


boolean urlEquals(URL url1, URL url2) { return url1.equals(url2); }
