java.util.Set (was: An Exception class cannot contain java.util.Set)
> An Exception cannot be marshalled if contains a field of type java.util.Set
> ----------------------------------------------------------------------------
>
> Key: CXF-4502
> URL: https://issues.apache.org/jira/browse/CXF-4502
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime, JAXB Databinding
> Affects Versions: 2.6.1
> Reporter: Peter Szanto
> Priority: Critical
>
> If I have an Exception that has a Set field like this :
> private Set<Integer> references;
> public Set<Integer> getReferences() {
> return references;
> }
> public void setReferences(Set<Integer> references) {
> this.references = references;
> }
> then when I throw it I get the below exception :
> Caused by: java.lang.IllegalArgumentException: Argument is not an array
> at java.lang.reflect.Array.getLength(Native Method)
> at
> org.apache.cxf.jaxb.JAXBEncoderDecoder.writeArrayObject(JAXBEncoderDecoder.java:423)
> at
> org.apache.cxf.jaxb.JAXBEncoderDecoder.marshallException(JAXBEncoderDecoder.java:389)
> Looking at the source of JAXBEncoderDecoder.writeArrayObject it is quite
> obvious that List is explicitly handled, but handling a Set is missing.
