This simple test breaks:
import java.time.Instant;
public class PacoTest {
private static class Pojo {
Instant instant;
public Pojo() {
this.instant = Instant.now();
}
}
@Test
public void paco() throws IOException {
Coder<Pojo> coder = AvroCoder.of(Pojo.class);
FileOutputStream fos = new FileOutputStream("t.tmp");
ObjectOutputStream oos = new ObjectOutputStream(fos);
coder.encode(new Pojo(), oos);
oos.close();
FileInputStream fis = new FileInputStream("t.tmp");
ObjectInputStream ois = new ObjectInputStream(fis);
System.out.println(coder.decode(ois));
ois.close();
}
}
