Command line used for generation

java -jar swagger-codegen-cli-3.0.2.jar generate -i test.yaml -l jaxrs-spec --api-package=api --model-package=model

Steps to reproduce

Execute command line above. Compile error occurs because of a unexpected line break.

following overloaded methods fixes the bug:

public CodegenParameter fromRequestBody(RequestBody body, Map<String, Schema> schemas, Set<String> imports) {
        CodegenParameter codegenParameter = super.fromRequestBody(body, schemas, imports);
        codegenParameter.description = this.escapeText(codegenParameter.description);
        return codegenParameter;
    }

Start at DefaultCodeGenConfig and the jaxrs-spec generator's fromRequestBody entry point, then reproduce the provided command with the OpenAPI declaration. Verify how request-body descriptions are handled and ensure the generated model output no longer contains an unexpected line break or compilation error.
