[jira] Commented: (NUTCH-755) DomainURLFilter crashes on malformed
URL
[ https://issues.apache.org/jira/browse/NUTCH-755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12783299#action_12783299 ]
Andrzej Bialecki commented on NUTCH-755:
-----------------------------------------
I could not verify that the filter indeed crashes - it simply prints the exception and then returns null, as you suggested.
