      Description

      I found a ClassCastException when using the COUNT function, the criteria API, and the QueryCache is enabled. I'll post a simple unit test shortly.

      <openjpa-2.1.0-SNAPSHOT-r422266:984243 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: Failed to execute query "null". Check the query syntax for correctness. See nested exception for details.
