Case/when in criteria with string literal result fails type checking
Description
The strings in the criteria query are always transformed into parameters, even if you use CriteriaBuiler#literal().

There is already a PR open with a test case, but it probably needs to be rebased to 5.0 https://github.com/hibernate/hibernate-orm/pull/801
New PR off 5.0
Trying to understand. So does this fail on 5.0? your comment makes me think it works.
Steve, this causes the exception in either version:
This is a workaround for both versions (using a number as literal):
This is a workaround only for 5.0.2 (using a Java boolean literal directly instead of wrapped by cb.literal()):
Any chance of having this fixed on 4.3 series?
