    Fix inconsistent writeEvent and readEvent in default serialization (#15740)
    
    The default implementation of ObjectOutput.writeEvent calls 
writeObject(data),
    while ObjectInput.readEvent uses readUTF(). This causes 
IndexOutOfBoundsException
    in components like dubbo-serialization-fury.
    
    Change writeEvent to writeUTF(String) to match readEvent.
    
    Fixes #15737
