Description

Any class with a simple primitive (such as long, or int) cannot be deserialized. For example, the following code:

    ObjectInputStream ois = null;
    try {
      ois = new ClassLoaderObjectInputStream(getClass().getClassLoader(), new ByteArrayInputStream(bytes));
      return (T) ois.readObject();
    } catch (ClassNotFoundException e) {
      LOGGER.error("Deserialization failed for {}", objectClass, e);
    } catch (IOException e) {
      LOGGER.error("Deserialization failed for {}", objectClass, e);
    } finally {
      if (ois != null) {
        try {
          ois.close();
        } catch (IOException ignored) {
        }
      }
    }

Will fail if bytes represents a byte[] of the serialized version of the following class:

public class Foo {

  private static final long serialVersionUID = 1L;

  private long thisFieldWillCauseCLOISToFail;

  // class logic, ctors, etc...

}

With the following stacktrace:
