Hard crash when attempting to write from Spreadsheet component

Hi,

I'm new to the component and just experimenting.  I'm trying to edit and save a spreadsheet and get a hard crash when trying to write the spreadsheet.

Here's the code (nothing special, I think)

                @Override
                public void buttonClick(ClickEvent event) {
                    try {
                        spreadsheet1.write(fileName);
                    } catch (FileNotFoundException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            });

fileName is the name used to open the spreadsheet originally.

I'm running this in Eclipse Luna, Java 1.6, Vaadin 7.5, Mac OSX, Tomcat 6.  I get a popup saying that Bootstrap has quit unexpectedly.  In the Eclipse console I get only:

Invalid memory access of location 0x10c609ca0 rip=0x102f3b65b

The file is an .xlsx with multiple sheets and some intricate formatting.

I've traced the crash as far as the bolded line below in POIXMLDocument

    public POIXMLProperties getProperties() {
        if(properties == null) {
            try {
                properties = new POIXMLProperties(pkg);
            } catch (Exception e){
                throw new POIXMLException(e);
            }
        }
        return properties;
    }

I'll go back and try with a simpler spreadsheet, but I'd really like to know what's going on here before I build up anything around the component.

Thanks,
Bill

I am facing the same problem can you please explain how did you solve it.

I was really, really disappointed not to have any support from Vaadin about this and more or less dropped the project.  It's been a while and I don't remember much, but I found this code, which did work (though it's ugly) as far as I recall.

buttonSave.attach();
            buttonSave.addClickListener(new Button.ClickListener() {
                
                @Override
                public void buttonClick(ClickEvent event) {
                    try {
                        // Overwriting seems to be a problem -- delete it first
                        new File(fileName).delete();
                        spreadsheet1.write(fileName);
                    } catch (FileNotFoundException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    
                }
            });

        }
