This will work since the owner module opens that package to the java.persistence module. As part of that process they can use the addOpens method on the client module owner to open the owner package to the Hibernate module. Fieldset (Object object, Object value) sets the field represented by this Field object on the specified object argument to the specified new value. Then we make the field accessible using tAccessible (true). In this case the mechanism could be employed as follows (quoted almost verbatim from the proposal):Ī JPA entity manager is created via one of the Persistence::createEntityManagerFactory methods, which locate and initialize a suitable persistence provider, say Hibernate. To make any private field accessible, we have to call the FieldsetAccessible method: In the above example, we first specify the field that we want to retrieve name by using the ClassgetDeclaredField method. CallerSensitive public Field getDeclaredField(String name) throws. Java Reflection - Class. The descriptor is compiled from a module-info.java file that defines a module’s name, its dependencies on other modules, and the packages it makes available: module some. In this page you can find the example usage for java.lang Class getDeclaredField. The Java Platform Module Saloon (JPMS) is introducing the concept of modules, which in the end are just regular JARs with a module descriptor. Let me set the scene of how the module system implements strong encapsulation and how that clashes with reflection.
