[Bug]: Calling a Java custom PTransform from Go using xlang fails on Dataflow Runner

### What happened?

As mentioned in #22931 - I am testing xlang support for the Go Runtime. I first was doing it wrong, using the Go direct runner, but then I moved on to test with the Dataflow runner.

I noticed that on Dataflow Runner, I could call a custom [Java Ptransform](https://github.com/ronoaldo/micro-beam/blob/main/05_xlang/java/src/main/java/com/ronoaldo/SplitWordsFromJava.java) from [Python](https://github.com/ronoaldo/micro-beam/blob/main/05_xlang/pipeline.py):


However,I could not call the same PTransform [from Go](https://github.com/ronoaldo/micro-beam/blob/main/05_xlang/go/pipeline.go). To submit the job, I started the Java expansion service as I did for the Python run, and called my Go pipeline. I see that the expansions service is called from Go, that the Go runtime stages the .jar files into Cloud Storage, but then the pipeline fails:


The only error message available is:

```

Look in previous log entries for the cause of each one of the 4 failures. For more information, see https://cloud.google.com/dataflow/docs/guides/common-errors. The work item was attempted on these workers:

Here is a full [pipeline log](https://docs.google.com/spreadsheets/d/1OFKBdDiHsz2ZAu5K_DjP4g15Wr2tr3rroyLN3qmts8o/edit?usp=sharing) and [worker logs](https://docs.google.com/spreadsheets/d/1aN8ycCBvs3tJljZ2gN2J0rv8GypQxebIcfM7tygGEeU/edit?usp=sharing) downloaded from Logs explorer.

Is this an actual bug or a unsupported workflow? I am trying to follow the Multi language pipelines section of the [Beam Programming Model docs](https://beam.apache.org/documentation/programming-guide/#multi-language-pipelines), regarding expose the Java PTransform (which I assume is correct since calling from Python works) and consuming it from Go, which I'm not sure if I missed any important steps.
