Description

Description

The java8 parameter in the spring generator is ignored, always behaves as true. It doesn't matter that it's specified explicitly or not. The generated code always contains Java 8 default interfaces.

Swagger-codegen version

Latest from master.

Command line used for generation

java -jar swagger-codegen-cli.jar generate -i swagger.json -l spring -o build -D hideGenerationTimestamp=true --invoker-package custom.package --model-package custom.package.model --api-package custom.package.api --additional-properties dateLibrary=java8-localdatetime,basePackage=custom,configPackage=custom.swagger,useBeanValidation=true,java8=false

Steps to reproduce

Execute the given command with any valid JSON file.

Suggest a Fix

I guess the issue is in the SpringCodegen.java, but haven't checked thoroughly.

Research direction

Reproduce the issue with the provided swagger-codegen command and inspect SpringCodegen.java, focusing on how the java8 additional property is read. Done means setting java8=false changes the generated Spring output so it no longer contains Java 8 default interfaces.
