Java Reflection, and Searching for fields

I am trying to search for specific fields (int[] type) that are loaded into memory from an applet that contain specific data. I know I can use reflection to this but there are hundreds of classes with many fields within each one. I have tried to recursively do this but the stack size is too small. I am capable of using find the memory addresses using cheat engine, but I believe the garbage collector is moving the data around so I can't use Unsafe. Does anybody know of any other way I can find the fields I am looking for given the data contained within them?
