If the WHERE condition contains a class name of an entity then the class name will be replaced with the full qualified class name.

Example:

de/container/Phase.java with a field comment.
The WHERE condition comment LIKE 'This is a test, Phase 1' will lead to a completely wrong HQL statement:
SELECT phase FROM de.container.Phase phase WHERE phase.comment LIKE 'This is a test, de.container.Phase 1'

The correct HQL statement should be:
SELECT phase FROM de.container.Phase phase WHERE phase.comment LIKE 'This is a test, Phase 1'
