   I was able to "bend the spoon" by java reflection and set the package private things to accessible, or writing an own `CustomPulsarWriter` in the `package org.apache.beam.sdk.io.pulsar;`  to extend abstract classes.. But now
   ```
   
   Exception in thread "main" java.lang.IllegalArgumentException: org.apache.beam.sdk.io.pulsar.WriteToPulsarDoFn: Non-splittable, but annotated as @UnboundedPerElement
