NPE in subquery

[Rajeev Jha <jh...@gmail.com>]

Hi
I have a very simple sub query. when I try to execute this sub query I
get NPE . looking at stack trace it seems to come from query
expression parser. The JQL is

 select stgrp from  Stagegroup stgrp  " +
			" where stgrp.dumpId = :dumpId and stgrp.name  "  +
			" IN ( select xname from group grp  " +
			" where  grp.prop1 = :value1)

I have also looked at openJPA-16 and OpenJPA-157. I am not supplying
null values anywhere. is this some known issue , any further clues or
how I can go about making sure its a code bug and not openJPA or
vice-versa ?

openJPA version is => openjpa-1.0.1-r420667:592145

.
