As a workaround you can use: criteriaBuilder.coalesce(root.get(attribute),criteriaBuilder.literal(0d)) Setting target and priority.

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.
