> Key: CAMEL-26220
> URL: https://issues.apache.org/jira/browse/CAMEL-26220
> Project: Camel
> Issue Type: Bug
> Components: camel-ai
> Reporter: Claus Ibsen
> Assignee: Andrea Cosentino
> Priority: Major
> Fix For: 4.24.0
>
>
> Found while adding the catalog body types of ibm-watson-discovery
> (CAMEL-24961, PR #28402).
> h4. 1. query always fails with NoClassDefFoundError
> com/google/gson/internal/$Gson$Types
> This is a dependency alignment issue. camel-parent manages {{gson}} at 2.14.0
> ({{parent/pom.xml}}, main 2a465aa4814c, line 224), and the IBM Watson SDK
> 16.2.0 brings {{com.ibm.cloud:sdk-core}} 9.20.0, whose
> {{DynamicModelTypeAdapterFactory}} still uses the Gson internal class
> {{$Gson$Types}}, renamed to {{GsonTypes}} in newer Gson. Parsing the query
> response therefore fails in {{WatsonDiscoveryProducer.query}} (line 89) with
> {{InvalidServiceResponseException}} caused by {{NoClassDefFoundError:
> com/google/gson/internal/$Gson$Types}}, even for
> {{\{"matching_results":0\}}}. Other operations whose response models use
> dynamic properties (and camel-ibm-watsonx-data, which uses sdk-core 9.18.4)
> may fail the same way. Checked on 4.24.0-SNAPSHOT with a JDK HttpServer stub
> as the Discovery service.
> Proposed: align the versions: manage {{com.ibm.cloud:sdk-core}} at 9.24.3 or
> later (these use {{GsonTypes}}) in the camel-ibm modules, or upgrade the IBM
> SDKs to versions built on it, and add a test that parses a query response.
