StackOverflowError Jasper Reports

Boa Noite Galera,

Poderiam me ajudar com um erro que to tendo ao utilizar o Jasper?
Criei um relatório, algo simples, exibe alguns dados e tem dois sub reports, que recebem listas de strings.

Porem, ao usuário clicar em imprimir, gera esse erro abaixo e o relatório não é gerado.
