Hmm.. well when I was unserializing and casting the objects into ArrayLists when making the LevelDesigner, I ran into this issue as well.

I recompiled that file with XLint, here's what I got:

C:\Users\Micah Stairs\workspace\FruitFever\src>javac InformationStorer.java -Xlint:unchecked
InformationStorer.java:86: warning: [unchecked] unchecked conversion
        fileHashMap = (HashMap) inStream.readObject();
                      ^
   required: HashMap<String,Object>
  found:    HashMap
 1 warning

Changing line 86 to "fileHashMap = (HashMap<String, Object>) inStream.readObject();", I get a different error. This one is trickier to figure out.

C:\Users\Micah Stairs\workspace\FruitFever\src>javac InformationStorer.java -Xlint:unchecked
InformationStorer.java:86: warning: [unchecked] unchecked cast
        fileHashMap = (HashMap<String, Object>) inStream.readObject();
                                                                   ^
