Michael Dick commented on OPENJPA-1992:
---------------------------------------
Thanks for the patch. Could you also provide a testcase the reproduces the
error?
The JPA spec does indicate that input parameters will start with 1 (section
4.6.4.1), but we should at least fail in a more informative way.
> java.lang.ArrayIndexOutOfBoundsException if positional parameter are not
> started from 1

> 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].
