Problem upgrading from jdk 1.2 to jdk 1.3.1

[Soraya Camarero]

Hi!. We have compiled ourclasses with jdk 1.2, and they work OK. The problem is that now we have to compile them with jdk 1.3.1. We can compile them OK, but they don't work correctly. We get the following error: "arrayIndexOutOfBounds". We don't know if there is a problem about upgrading code from jdk 1.2 to jdk 1.3.1. We have used FOP 1.20.0. Thank you!.
