Description

Issue #1423 was fixed in 3.3.3 with PR #1426.
We updated the generator to 3.3.4 and the issue occurs again.

openapi-generator version

3.3.4

OpenAPI declaration file content or url

cf open attached file.

Command line used for generation

java -jar ./openapi-generator-cli-3.3.4.jar generate -i yaml/TS29510_Nnrf_NFManagement.yaml -g jaxrs-resteasy -o generated-files-3.3.4

Steps to reproduce

1 - unzip the attached file

2 - copy the openapi-generator-cli-3.3.3.jar and openapi-generator-cli-3.3.4.jar files into the directory openapitools-generator-#2089

3 - go to openapitools-generator-#2089 directory

4 - generate the source code files with openapi-generator-cli-3.3.3.jar file
java -jar ./openapi-generator-cli-3.3.3.jar generate -i yaml/TS29510_Nnrf_NFManagement.yaml -g jaxrs-resteasy -o generated-files-3.3.3

5 - generate the source code files with openapi-generator-cli-3.3.4.jar file with same yaml files as above
java -jar ./openapi-generator-cli-3.3.4.jar generate -i yaml/TS29510_Nnrf_NFManagement.yaml -g jaxrs-resteasy -o generated-files-3.3.4

6 - Do a diff about generated model files between both output directories generated-files-3.3.3\generated-files-3.3.4\src\gen\java\org\openapitools\model\ and generated-files-3.3.4\generated-files-3.3.4\src\gen\java\org\openapitools\model.
The generated java class file LinksValueSchema.java misses in generated-files-3.3.4.

Start with the attached TS29510_Nnrf_NFManagement.yaml and the jaxrs-resteasy generation command, then compare the generated model files from versions 3.3.3 and 3.3.4. Investigate why LinksValueSchema.java is absent from the 3.3.4 output; done means the model is generated consistently with the fixed 3.3.3 result.
