Subject [jira] Commented: (UIMA-1747) TikaAnnotator: null pointer exception in MarkupHandler.populateCAS
Date Mon, 22 Mar 2010 03:58:27 GMT

    [ https://issues.apache.org/jira/browse/UIMA-1747?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12848027#action_12848027
] 

Greg Holmberg commented on UIMA-1747:
-------------------------------------

This is due to this line, 147 in MarkupHandler.java, returning null:

    Type attributeType = cas.getTypeSystem().getType("org.apache.uima.AttributeFS");

The problem is that the class name string is incorrect.  It should be "org.apache.tika.uima.AttributeFS".
 Same for the line above, but that variable is never used, so it doesn't matter.
