Description

The method writeObject(final ObjectOutputStream out) of the class org.apache.logging.log4j.message.StringFormattedMessage does not write the stringArgs array into the output stream. This causes readObject(final ObjectInputStream in) to throw an EOFException when trying to deserialize.

There is another bug in the same method. The line stringArgs[i] = obj.toString(); throws a NullPointerException when obj is null.
