This proved to be quite popular, drawing in many of the 582,797,754 Jaxes Pavan living on Coruscant, until the incident involving Jax Pavan 582,797,631, which being an open case of fraud, threatened to end Jax Pavan 21's career.
Then in a stroke of genius, 21 managed to placate all of the 582,797,753 other human males named Jax Pavan on Coruscant bby coming up with The Great Jax Pavan Sexual Lottery (every Friday night from 6 pm in the Blue Lounge) wherein females from all over the Galaxy were invited to sleep with any Jax Pavan present and at the end of the night if the number called was the Jax Pavan you slept with, you won! The Jax Pavans on Coruscant pretty much unanimously agreed that this was a good idea, and Jax Pavan 21 was awarded the title Jax Pavan of the Year in 14 ABY.
