I have two projects set up as client and server using Spring in Java 7 update 51. The underlying system is Scientific Linux 6.5 (kernel version 2.6.32-431.23.3.el6.x86_64). The used libraries are jasperreports-5.6.0, iText-2.1.7, jcommon-1.0.15 and jfreechart-1.0.12 .
The client reads a JasperReports design document (.jrxml) into a byte array and sends it to the server. The server then creates a JasperPrint object:
InputStream inputStream = new ByteArrayInputStream(reportDesignByteArray);
jasperReport = JasperCompileManager.compileReport(inputStream);
jasperPrint = JasperFillManager.fillReport(jasperReport, parameter, dataSource);
This object is returned to the client via RMI. At this point I am getting the following error (JasperPrint is derived from Serializable though):

I tried to perform the serialization myself with the following procedure:
Server
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
objectOutputStream.writeObject(jasperPrint);
byte[] serializedPrint = byteArrayOutputStream.toByteArray();
Client
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(serializedPrint);
ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
jasperPrint = (JasperPrint) objectInputStream.readObject();
I still get the same error. However, it works in a local unit test, so the error only appears when using RMI. I also checked the serialized object regarding size and SHA-1 hash on the server and the client side. They are identical.
Do you have any suggestions how to fix this?
The problem was solved by updating JFreeChart to version 1.0.13 on both server and client side.
