Subject [jira] [Created] (CASSANDRA-9077) NPE
Date Tue, 31 Mar 2015 04:48:53 GMT
dan jatnieks created CASSANDRA-9077:

             Summary: NPE
                 Key: CASSANDRA-9077
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: dan jatnieks
            Priority: Minor

I am seeing an NPE on the latest 2.1 branch with this sequence of deletes from a list - first
delete the entire list, then attempt to delete one element.

I expected to see {{List index 0 out of bound, list has size 0}} but instead got an NPE.

cqlsh:frozen_collections> DELETE l[0] FROM t WHERE id = 'user';
ServerError: <ErrorMessage code=0000 [Server error] message="java.lang.NullPointerException">
cqlsh:frozen_collections> DELETE s FROM t WHERE id ='user';
cqlsh:frozen_collections> DELETE s['1'] FROM t WHERE id = 'user';{noformat}

It appears the {{DELETE emails...}} directly followed by {{DELETE emails[0]...}} is the offending
sequence. Either one alone works fine, as does adding an intervening insert/update.
