Expression Language 3.0 feature functions

The Expression Language (EL) 3.0 feature provides full support for the EL 3.0 specification.

Descriptions of EL 3.0 functions are provided in the EL 3.0 specification and are not fully described here. However, some of the key enhancements include the following:

Important: There is a change in the EL 3.0 feature that might break existing applications. The default coercion for nulls to non-primitive types (except String) returns nulls. For instance, a null that is coerced to a Boolean now returns a null value, while a null that is coerced to Boolean returns false. The following code example describes this scenario:
Integer number=null;
factory.coerceToType(number, java.lang.Double.class)

For more information refer to: JSR-000341 Expression Language 3.0 Specification.
