I can see that FBSimpleDataSource supports set/get of TPB Parameters via setTpbMapping() and setTransactionParameters().  How do I set the following parameters on an FBSimpleDataSource connection?

I need to set the following:

isc_tpb_nowait, isc_tpb_read_committed, isc_tpb_no_rec_version

I've already figured out that these are int constants found in the TransactionParameterBufferImpl class but I can't figure out how to set them into connection properties at runtime.  

It looks like I can setup a Properties bundle or define one on the fly.  But how do I specify a collection of parameters?

It looks like I'd want:TransactionParameterBufferImpl.NOWAIT, TransactionParameterBufferImpl.READ_COMMITTED and TransactionParameterBufferImpl.NO_REC_VERSION.

I'm using HikariCP for my Connection Pool.
