I am having trouble opening multiple objects that were serialized into a single .bin file. Right now, I can only get one object to be read in when I attempt to open the file. After the first object is read, the error message is displayed (and no further objects are read). My code looks like the following:
val ois = new ObjectInputStream(new BufferedInputStream(newFileInputStream(chooser.selectedFile)))
val toRead:Int = ois.readInt()
for (i <- 0 to toRead) {
ois.readObject() match {
case anObject : myObject =>
aMutableBuffer += anObject
case _ =>
}
ois.close()
}
The error that I am getting is a lot of the following:

This only happens when I read in an object to my buffer that keeps track of the objects. Moreover, I am able to save the file correctly (as I have done tests to ensure everything got there). Anyone have any ideas what is going on here?
