StackOverflowException on 32bit java - not 64bit

Question

I have written a desktop application which is JavaFX based, developed on NetBeans 7.4. I'm using Glassfish to pool jdbc connections and JMS traffic. Development is on a Win 7 64bit system, using 64bit java 1.7_51. One of my users has a 32bit win 7 machine, and the application refuses to run correctly on his machine. There are actually 2 glassfish servers, each providing data connectivity from a different logical company. All of the server code on the two glassfish servers is built from the same code base. The application, running on the 32bit java, get a StackOverflowException when reading data from one of the servers but not the other, so I assumed it was somehow related to the deployment of the server. When I could find nothing there, I then serialized the data to a file, and when reading in the data from the file, the same dataset gives me the overflow. Again, this is only in the 32bit version of java. I have rebuilt the application using a 32bit java jdk, and the error persists. Running the 32bit jar on a 64bit java jvm does not have a problem. The stack trace when trying to read from the database:

The fact that it happens regardless of where the data is stored makes me think it is the data, but doing a manual examination of all of the data (which thankfully is only about 200 - 500 rows in 4 tables), it wasn't that bad.

So, I'm here looking for suggestions as to what the underlying cause might be. To recap, it doesn't matter if I build with 32 or 64 bit jdk, the only thing that matters is what jvm I use. A 32 bit jvm always crashes reading the same data; even when running on a 64 bit OS. Stack overflows usually point to some type of run-away recursion, but there is nothing like that in the code. The database fetch is a simple "select * from..." and the deserialization of the data from a file is a straight read from an ObjectInputBuffer into a ArrayList<>. Thanks for any help.

Sorry, forgot some code - Here is the file deserialization:

        try (FileInputStream fin = new FileInputStream(home.toString() + "/products.ser"); ObjectInputStream oin = new ObjectInputStream(fin)) {
            logger.info("Entering read archive products");
            ArrayList<Product> aInputList = (ArrayList<Product>) oin.readObject();
            if (pricingProductTableList == null) {
                pricingProductTableList = FXCollections.observableArrayList(aInputList);
            } else {
                pricingProductTableList.clear();
                pricingProductTable.getItems().clear();
                pricingProductTableList.addAll(aInputList);
            }
            pricingProductTable.getItems().setAll(pricingProductTableList);
            oin.close();
            fin.close();
        } catch (Exception ex) {
            DialogFX error = new DialogFX(DialogFX.Type.ERROR);
            error.setMessage("Invalid Selection " + ex.getMessage());
            error.showDialog();

        }
        try (FileInputStream fin = new FileInputStream(home.toString() + "/chemicals.ser"); ObjectInputStream oin = new ObjectInputStream(fin)) {

            if (pricingChemicalTableList == null) {

            error.showDialog();
            return;
        }
        try (FileInputStream fin = new FileInputStream(home.toString() + "/adhesives.ser"); ObjectInputStream oin = new ObjectInputStream(fin)) {
            ArrayList<Adhesive> aInputList = (ArrayList<Adhesive>) oin.readObject();
            logger.info("Entering read archive adhesives");
            if (pricingAdhesiveTableList == null) {
                pricingAdhesiveTableList = FXCollections.observableArrayList(aInputList);

There is no such thing as a "32-bit jar". All pure java-files are (meant to be) independent of the architecture they are built on - that's what "write once run anywhere" is all about. The difference between 32 and 64 bit depends only on the VM running the code.

If you didn't adjust your stack-size explicitly a 32bit-Vm is much more likely to run into a StackOverflowError since it's default stack-size per thread is much smaller (see here):

In Java SE 6, the default on Sparc is 512k in the 32-bit VM, and 1024k in the 64-bit VM. On x86 Solaris/Linux it is 320k in the 32-bit VM and 1024k in the 64-bit VM.

On Windows, the default thread stack size is read from the binary (java.exe). As of Java SE 6, this value is 320k in the 32-bit VM and 1024k in the 64-bit VM.

You can see in the exceptions stacktrace, that the call-hierarchy is pretty deep since you seem to be deserializing a complex object-tree and the 320k-stack doesn't seem to be able to handle this. To solve your problem you could try setting the -Xss-parameter to a higher value.
