ObjectEncoderOutputStream Out Of Memory Exception possible?

Question

I noticed that ObjectEncoderOutputStream uses ObjectOutputStream . Traditionally ObjectOutputStream can cause an OOME if it's not reset on a regular basis. Is ObjectEncoderOutputStream susceptible to this?

Answer 1

No , the ObjectEncoderOutputStream is not susceptible to the same problem, because of the way it uses the ObjectOutputStream .

For each writeObject call a new ObjectOutputStream (specifically a CompactObjectOutputStream ) is created to write that single object and then it is closed again.

Thus, no ObjectOutputStream ever holds on to old references and thus doesn't cause a OOM this way.
