I can construct an instance of the generated Java class which contains an OpenType value without any problem and isValid() returns "true", But it throws an EncodeFailedException when I try to encode it. The error message is: E0090E: Length of encoded data of OpenType is 0; check field 'content' (type: OpenType) of field 'contentInfo' (type: ContentInfo) of PDU 'PInitRes'.

The most likely reason for an EncodeFailedException where the OpenType appears to have a length of 0 (zero) is that automatic encoding is not enabled.

Call Coder.enableAutomaticEncoding().
