setBlob(InputStream) not supported?

I've got a web service that is coded to stream data into a database
blob via jdbc, and which uses, therefore, the setBlob(InputStream) API
on the prepared statement.

I was rewarded in the very latest driver with a 'not yet implemented'.
Is there a recommended workaround for this?
