validateOAS not set in OpenApi

[harveycggit]

Setting validateOAS to false in a jenkinsfile appears to make no difference because the assignment appears to be missing in OpenAPI.

I believe

OpenAPI(Map conf) {
    assert conf.filename != null
    assert conf.content != null
    this.filename = conf.filename
    this.content = conf.content
} 

should be
OpenAPI(Map conf) {
assert conf.filename != null
assert conf.content != null
this.filename = conf.filename
this.content = conf.content
this.validateOAS = conf.validateOAS
}

Changing that appears to make the param work successfully.

Thanks,
Charles
