Subject [jira] [Commented] (OPENJPA-1992) java.lang.ArrayIndexOutOfBoundsException if positional parameter are not started from 1
Date Sat, 07 May 2011 19:36:03 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13030396#comment-13030396

Michael Dick commented on OPENJPA-1992:
---------------------------------------

I agree. This is about detection and producing an informative error message. At this time
I don't think we can or should support numeric parameters that start at any point.

> Query q = em.createQuery("SELECT x FROM Magazine x WHERE x.title = ?2 and x.price >
?3");
> q.setParameter(2, "JDJ").setParameter(3, 25.0);
> When the query is executed, java.lang.ArrayIndexOutOfBoundsException will be thrown.
Since "JDJ" and "25.0" will be stored in arr[0] and arr[1] (when arr.size =2) but the query
execution code tries to get them via arr[2] and arr[3].
