Running the following query task against my database:
<htools destdir="${sql}">
<classpath refid="classpath.apps"/>
<annotationconfiguration configurationfile="${src}/hibernate.cfg.xml"/>
<query destfile="sql.log">from Note</query>
</htools>

Fails with the attached lavish stack trace. The cause of the problem appears to be a single character typo in:
org.hibernate.tool.hbm2x.QueryExporter on line 47 where a variable "iter" is used instead of "iter1".

There also appears to be a bug preventing the nested <hql> tasks from working, but I'm uncertain if that's an artifact of this problem or a separate issue.
