Description Marc Nuri CLA 2011-03-28 05:15:37 EDT 
When using the method coalesce with an Expression and a literal such as: 

criteriaBuilder.coalesce(root.get(attribute),0d) 

The following exception is thrown:
Caused by: java.lang.ClassCastException: java.lang.Double cannot be cast to org.eclipse.persistence.internal.jpa.querydef.InternalSelection 
        at org.eclipse.persistence.internal.jpa.querydef.CriteriaBuilderImpl.coalesce(CriteriaBuilderImpl.java:2117)

Literals should be admitted in the coalesce method of CriteriaBuilder interface implementation.
Comment 1 Marc Nuri CLA 2011-03-28 05:18:05 EDT 
As a workaround you can use:
criteriaBuilder.coalesce(root.get(attribute),criteriaBuilder.literal(0d))
