Is serialization implementation may cause inadequate heap size memory?

Is it possible?

[Sagar Rohankar]

Serialization is simply, storing and retrieving the objects and it should not cause the inadequate heap size, especially during deserialization of objects. Leave everything else to the GC.

see,serialization is the process which do the object caching,so if the cached object not go for deserialization for a long time which might lead to inadequate heap size

But "caching space" is not necessarily be the heap space, because when you want to serialize your objects to the output stream then one might uses file or sockets to flattened the objects, no one uses JVM memory to serialize objects, that's not Serialization concept is used for.

May be reading this article helps you to understand most of the things !

An ObjectOutputStream needs a cache of every object you write to it, so that if you write the same object again, it can substitute a reference to the earlier object, rather than writing a new copy. You'd think that ObjectOutputStream would use WeakReferences in that table, but it does not. Therefore, if you keep an ObjectOutputStream open for a long time, it can be a source of memory leaks, since objects that would otherwise be garbage collected can be retained because of the reference in that cache.

So yes, serialization can cause you to run out of memory, but not for any of the reasons previously discussed in this thread.

Hi friends,

Thanks for the help in my clarification
