JsonbException while marshalling: Invalid count of arguments for setter

[minfrin]

I have a large project that uses cxf-xjc-plugin to autogenerate JAXB bindings for a series of XSDs, and this is able to marshall XML without a problem.

We recently tried to use Jersey's JSON marshalling option, and this has been failing for us with the following exception below.

The setter javax.xml.datatype.XMLGregorianCalendar.setTime(int,int,int) is a valid setter from the perspective of the docs for XMLGregorianCalendar, does this look familiar to anyone?

I've run into this same problem marshalling some model classes that work fine with Jaxb.
It feels like having any method that starts with 'set' is being interpreted as a property setter. Even when the method (in our case) takes zero arguments and should likely be ignored (ie. not related to a marshallable property).

I just ran into this issue with my custom model classes. I have some REST representational classes with utility methods that starts with "setXXXXXXX(parameter1, paramater2, .....).
And I am getting this exact message.
15:26:32,588 SEVERE [org.eclipse.yasson.internal.Marshaller] (default task-2) Generating incomplete JSON 15:26:32,593 SEVERE [SYNEKUS] (default task-2) Unhandled error: RESTEASY008205: JSON Binding serialization error javax.json.bind.JsonbException: Invalid count of arguments for setter:

IMHO I think Yasson should validate that the "set" methods have one and only one parameter before invoking them. It will be a hassle for people coming from Java EE7+Jackson (as I am).

Should I open a new issue for this ?

Regards!
Cristhian.

I found that the number of arguments is being validated in

yasson/src/main/java/org/eclipse/yasson/internal/model/Property.java

Line 150 in a1f5120

throw new JsonbException("Invalid count of arguments for setter: " + getSetter());

It wouldn't be better to log a warning maybe ? It is blocking if I have a method starting with "set" and receiving multiple parameters. Another better option would be exclude this properties from being parsed at all maybe in

yasson/src/main/java/org/eclipse/yasson/internal/ClassParser.java

Line 55 in b1a8288

public void parseProperties(ClassModel classModel, JsonbAnnotatedElement<Class<?>> classElement) {

Sorry, please omit the previous comments, I just found out that it is fixed in master eaebfcb#diff-0b679cdd432a9709d06c281d3ac6656b

Hi @cristhiank ,
I have created new issue which is mainly focused on problem with "set" methods and multiple parameters.
This issue can be found here #152
