[dali-dev] Encountered exception but can't reproduce it

["Pascal Filion" <pascal.filion@xxxxxxxxxx>]

Hey guys,

While working on JPQL stuff, I hit this exception but when I tried to gather
the steps, I couldn't reproduce it. I hope someone can figure out the steps
required.

Basically, I had a Java source file opened, I think persistence.xml was also
opened. The JPA details view was opened as well. I changed the platform from
EclipseLink to Generic.

Pascal...
