Which possibilities else exists to control the deserialization?

My requirement was to made a snapshot of the application-state, but the deserialize fails with StackOverflowError.

In the test-phase these technics work fine, because the
result was a file with less then 2 MBytes.

Now it is near 10 MBytes.
After reviewing all comments about deserialization like

• writing smaller units (not possible!);
  
• try to use the flag -Xss, at least with 10M does not help;
