The Hibernate manual notes:

To enable property level lazy fetching, your classes have to be instrumented: bytecode is added to the original class to enable such feature, please refer to the Hibernate reference documentation. If your classes are not instrumented, property level lazy loading is silently ignored.

How to achieve this is explained in chapter 20.1.8. Using lazy property fetching of the manual. It requires a special build process.

You have to enable bytecode instrumentation to activate lazy loading for properties. If you don't have bytecode instrumentation enabled, Hibernate will ignore any properties about lazy loading (see the docs)
