Panic on CreateReadSession if ReadOptions not provided

[turb]

What happened?

When calling CreateReadSession with Java client without providing ReadOptions:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x17e2078]

goroutine 336 [running]:

What did you expect to happen?

Read session created without error.

How can we reproduce it (as minimally and precisely as possible)?

CreateReadSessionRequest request = CreateReadSessionRequest
      .newBuilder()
      .setReadSession(
        ReadSession
          .newBuilder()
          .setTable(
            s"projects/${tempTable.getProject}/datasets/${tempTable.getDataset}/tables/${tempTable.getTable}",
          )
          .setDataFormat(DataFormat.AVRO)
          // prevents panic: runtime error: invalid memory address or nil pointer dereference on bigquery emulator
          //.setReadOptions(TableReadOptions.newBuilder().build())
      )
      .setParent(s"projects/${tempTable.getProject}")
      .setMaxStreamCount(1)
      .build()

readClient.createReadSession(request)

Anything else we need to know?

Workaround: provide an empty ReadOptions (as commented out in example code).
