JavaFx - Caused by: java.lang.StackOverflowError

[Silva Mateus 0]

Olá estou com um problema em minhas classes Java. Quando tento criar um novo "Fornecedor", o console me resulta o Caused by: java.lang.StackOverflowError. 

Aqui estão as minhas classes que interagem entre si. Se alguém poder me auxiliar na resolução deste problema, agradeço.
