> POJO Cache 1.4.x adds interceptor changes during get operations to the undo list. This effectively prevents an object retrieved from a get() from being usable if a rollback occurs during the TX that contains the get. 
> For this, and other reasons, get operations should never rollback interceptor additions.
> Original report:
> In my cluster i have 2 PojoCache (REPL_SYNC,inactive on startup,transcational,replication version 1.4.0.GA). First i create one cache and fill it with data, then i create the second cache and force full state transfer using region activation. On the second cache, after it received the state, in a new transaction, i fecth an object from the cache and modify a map it contains and then rollback the transaction. After the rollback, *all* the objects in the seconds cache are corrupted: all properties values are now null!, (the other cache is not corrupted). Note, when modifing a primitive property and then rollback, the cache is not corrupted. What i found is that in the corrupted objects, the instanceAdvisor appendedInterceptors list is missing the CacheInterceptor.
> attached a unit test demonstrating this bug. The test is based on the distribution org.jboss.cache.aop.statetransfer.StateTransferAopTestBase unit test, to run it, add it to the distribution org.jboss.cache.aop.statetransfer tests package and run the tests.
