I looked into the code TransactionLog.java (branch_5_5) :: JavaBinCodec.ObjectResolver resolver = new JavaBinCodec.ObjectResolver() { @Override public Object resolve(Object o, JavaBinCodec codec) throws IOException { if (o instanceof BytesRef) { BytesRef br = (BytesRef)o; codec.writeByteArray(br.bytes, br.offset, br.length); return null; } // Fallback: we have no idea how to serialize this. Be noisy to prevent insidious bugs throw new SolrException(SolrException.ErrorCode.SERVER_ERROR, "TransactionLog doesn't know how to serialize " + o.getClass() + "; try implementing ObjectResolver?"); } };
While UUID implements serializable, so should be BytesRef instance to?? :: public final class UUID implements java.io.Serializable, Comparable<UUID> Can you share the payload with you are trying to update?
