I'm serializing an object graph in the android code and pass result to GAE servlet. While deserializing I sometimes get the following exception:
java.io.StreamCorruptedException: invalid type code: 71
I traced the problem down to one of the fields. If I set it to null or mark as transient the problem disappears. But, if I serialize/deserialize only this field - I don't see any problems as well.
Any ideas?
