[jira] Commented: (NUTCH-436) Incorrect handling of relative paths when the embedded URL path is empty

["Andrew Groh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NUTCH-436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12467883 ] 

Andrew Groh commented on NUTCH-436:
-----------------------------------

This is a bug in java.net.URL, specifically the URLStreamClass that it uses.  

new URL("http://a/b/c/d;p?q#f ","?y")

creates a URL object with a bad URL.
