Description

The following test fails:

@Test
public void foo() throws IOException {
    DateTime nowIn = DateTime.now();
    DateTimeWritable in = new DateTimeWritable(nowIn);

    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    DataOutputStream dataOut = new DataOutputStream(outputStream);
    in.write(dataOut);
    dataOut.flush();

    // read from byte[]
    DateTimeWritable out = new DateTimeWritable();
    ByteArrayInputStream inputStream = new ByteArrayInputStream(
      outputStream.toByteArray());
    DataInputStream dataIn = new DataInputStream(inputStream);
    out.readFields(dataIn);

    assertEquals(in.get(), out.get());
}

In equals(), the original instance has

ISOChronology[Europe/Berlin]

while the deserialized instance has

ISOChronology[+01:00]
