Hibernate NullPointerException on getNamedParameterExpectedType

I received this very cryptic message from a Hibernate query today:
java.lang.NullPointerException at org.hibernate.hql.internal.ast.ParameterTranslationsImpl.getNamedParameterExpectedType(ParameterTranslationsImpl.java:87) at org.hibernate.engine.query.spi.HQLQueryPlan.buildParameterMetadata(HQLQueryPlan.java:319) at org.hibernate.engine.query.spi.HQLQueryPlan.(HQLQueryPlan.java:124) at org.hibernate.engine.query.spi.HQLQueryPlan.(HQLQueryPlan.java:80) at org.hibernate.engine.query.spi.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:168) at org.hibernate.internal.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionImpl.java:219) at org.hibernate.internal.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:197) ...
A quick google search found this bug which basically says you have too many parenthesis.

So, watch your closing parenthesis because Hibernate doesn't know how to give helpful error messages.

Hibernate: Map Separate Date and Time Columns to a Date

I ran into a problem where I was trying to get Hibernate to map seperate date and time columns from an SQL Server to one Date object

In my query editor CAST(from_date AS DATETIME) + CAST(from_time AS TIME) worked just fine so I plugged it into a @Formula, but it turns out Hibernate really wanted to put the table alias in from of the keyword DATETIME(HHH-2967)

After some cursing at Hibernate I finally came up with a formula that works

Simply put, I'm just converting the date to a string and then concatenating the time as a string. Fairly simple, but a pain.
