Subject [jira] Commented: (JCR-888) javax.jcr.NamespaceException: : is not a registered namespace uri
Date Wed, 29 Apr 2009 10:12:30 GMT

    [ https://issues.apache.org/jira/browse/JCR-888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12704053#action_12704053
] 

Stefan Guggisberg commented on JCR-888:
---------------------------------------

in general a fix will have to make sure that the internal mapping of 
ns uri to integer is not affected, see  my previous comment [1]. 

ns uri's are internally assigned integer values. those integer values
are persisted in place of the ns uri for space efficiency. any change 
in this assignment logic might break backwards compatibility.

you might want to search for references/implementations of 
o.a.j.core.util.StringIndex.
