I found the answer, The mistake is on the below line of Payment POJO.

@GenericGenerator(name = "generator", strategy = "foreign", parameters = @Parameter(name = "property", value = "tickets"))

Here I specified like value = "tickets" which is invalid in this mapping. I have to specify like value = "ticket". This fixed it.
