Question

Answer 1

This fails due to the Context field in your class. Context objects are not serializable.

Per the Serializable documentation - "When traversing a graph, an object may be encountered that does not support the Serializable interface. In this case the NotSerializableException will be thrown and will identify the class of the non-serializable object."

You can either remove the Context field entirely, or apply the transient attribute to the Context field so that it is not serialized.

public class MyClass implements Serializable 
{
    ...
    public transient Context myContext;
    ...
}
