Resolved Issues

In addition to the features highlighted in the New and Noteworthy section this release also includes a substantial number of bug fixes and enhancement requests.

Property Name Generation from Introspector.decapitalize

The decapitalize method will now leave the property name in uppercase if the first and second characters are uppercase. EclipseLink will use the property name as ID, as detailed in the specification.

Note that this may require a change in some JPQL. For example, if previously you had a method with an annotation such as getCCustomers that would previously have had a property named cCustomers, you will now need to use property CCustomers.
