We are using Hibernate.initialize to make sure that the OneToMany relationship is initialized before it is getting cached. Our cache has a global maxBytesLocalHeap set, so a sizeof measurement takes place before caching. This works well and is fast on a 32-bit JVM, but on a 64-bit JVM the ObjectGraphWalker spends multiple minutes walking the object graph for the List and eventually hits the depth limit of 1000. I am a bit lost trying to figure out what is wrong (a heap dump captured via Visual VM does not seem to contain the objects currently on the stack). Is sizeof measurement any different between 32 and 64bit?
