----------------------------------------
Hi Michael,
This exception can be reproduced with the hellojpa sample by following Getting
Started with the Eclipse steps on
http://openjpa.apache.org/getting-started.html. After step 10, replace the
Main.java with the attached copy of Main.java, and then rerun step 9.
I noticed that spec indicates that input parameters will start with 1 in both
JPA spec(section 4.6.4.1) and EJB spec(section 9.2.6.4), but this exception
blocks our TCK, which expects "SELECT x FROM Magazine x WHERE x.title = ?2 and
x.price > ?3" can be successfully processed.
> java.lang.ArrayIndexOutOfBoundsException if positional parameter are not
> started from 1

> Key: OPENJPA-1992
> URL: https://issues.apache.org/jira/browse/OPENJPA-1992
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 2.1.0
> Reporter: Han Hong Fang
> Assignee: Michael Dick
> Attachments: Main.java, OPENJPA-1992.patch
>
>
> 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].
