> The onGet method in cache interceptors appears not to be called since version 2.9.0. Or at least, the API changed. I have the following code:
>         CacheConfiguration<Long, Object> cacheConfiguration = new CacheConfiguration<>();
>         cacheConfiguration.setName("PERSON_CACHE");
>         cacheConfiguration.setAtomicityMode(CacheAtomicityMode.ATOMIC);
>         cacheConfiguration.setIndexedTypes(Long.class, Person.class);
>         cacheConfiguration.setInterceptor(new CacheInterceptor<Long, Object>() \{
>             @Override
>             public Object onGet(Long aLong, Object p) {
>                 Person person = (Person)p;
>                 return new Person(new StringBuilder(person.getName()).reverse().toString(), person.getHeight());
>             }
>             @Override
>             public Object onBeforePut(Cache.Entry<Long, Object> entry, Object p) \{
>                 if (p.getClass().equals(Person.class)) {
>                     Person person = (Person)p;
>                     return new Person(new StringBuilder(person.getName()).reverse().toString(), person.getHeight());
>                 }
>                 else if (p.getClass().equals(BinaryObjectImpl.class)) \{
>                     BinaryObjectBuilder person = ((BinaryObject) p).toBuilder();
>                     String name = person.getField("name");
>                     person.setField("name", new StringBuilder(name).reverse().toString());
>                     return person.build();
>                 }
>                 else \{
>                     return null;
>                 }
>             }
>             @Override
>             public void onAfterPut(Cache.Entry<Long, Object> entry) \{
>                 // do nothing
>             }
>             @Override
>             public IgniteBiTuple<Boolean, Object> onBeforeRemove(Cache.Entry<Long, Object> entry) \{
>                 return new IgniteBiTuple<>(true, entry.getValue());
>             }
>             @Override
>             public void onAfterRemove(Cache.Entry<Long, Object> entry) \{
>                 // do nothing
>             }
>         });
> It reverses the name before storing it and reverses it again on a get. In 2.9.0 this works as expected. In every version since it fails. It reverses the string on a put but the onGet method never gets called.
