[jira] [Commented] (OODT-887) Prevent DNS resolution on URL Lookup

    [ https://issues.apache.org/jira/browse/OODT-887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14951662#comment-14951662 ]

---------------------------------

I've made a few commits on this:

Like it says in my final commit apart from the profile server I've not changed the API just converted to URI internally, but Sonar flags the issue as a blocker which I think is good because having to do a DNS lookup over the internet for example when looking at a hashmap of URLS is nuts, especially if your DNS is slow as a dog.

> Sonar flagged up an issue because URL.equals() dials up the network connection to check name resolution which is a bit weird and slow. Comparing URI's doesn't.
