Ich befürchte, du solltest ein flush für deinen ObjectOutputStream ausführen. Probier es mal damit!

-----------------
public ObjectOutputStream(OutputStream out)
throws IOException
Creates an ObjectOutputStream that writes to the specified OutputStream. This constructor writes the serialization stream header to the underlying stream; callers may wish to flush the stream immediately to ensure that constructors for receiving ObjectInputStreams will not block when reading the header.
