Subject [jira] Commented: (DIRSERVER-1180) NPE and hanging search request when using a filter with empty substring sequence
Date Tue, 08 Jul 2008 12:38:49 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-1180?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12611557#action_12611557
] 

Emmanuel Lecharny commented on DIRSERVER-1180:
----------------------------------------------

The test is blocking during the search, but as far as I can say, we don't receive anything
on the server side. It seems that we are blocked on the Sun JNDI layer, while trying to parse
the (cn=**) string.

I will try to characterize this.
