Ray cross language support doesn't support trace

Ray Core

I guess this is a Ray bug when calling Java actors from Python, with Ray.init have tracing_startup hook argument set. Java actor not able to initialized with exception “Cross language remote functions does not support kwargs”

It is easily reproducible with similar code like below

    ray.init(job_config=ray.job_config.JobConfig(
        code_search_path=["/Users/Shared/Projects/libs"]),
        _tracing_startup_hook="ray.util.tracing.setup_local_tmp_tracing:setup_tracing"
    )
    java_class = ray.cross_language.java_actor_class(
        "com.mycompany.ml.operators.FeatureFetcherOperator").remote("constructor argument 1")

    counter = counter_class.execute.remote("method argument 1")

And it will produce stack trace. Which the kwargs is set to be the tracing context.
