APACHE POI: java.lang.IndexOutOfBoundsException was occurred after closed the FileSystem

Issue
- I was created the extended class of [org.apache.tika.parser.microsoft.ExcelExtractor] same as below to extract the embedded documents of excel(*.xls) file.

    public class CustomExcelExtractor extends ExcelExtractor {
        private CustomAbstractPOIFSExtractor poi;
    
        public CustomExcelExtractor(ParseContext context, Metadata metadata, Path outputDir) {
            super(context, metadata);
            poi = new CustomAbstractPOIFSExtractor();
        }
    
        @Override
        public void parse(
                DirectoryNode root, XHTMLContentHandler xhtml,
                Locale locale) throws IOException, SAXException, TikaException {
    
            // Extract embedded documents
            for (Entry entry : root) {
                if (entry.getName().startsWith("MBD")
                        && entry instanceof DirectoryEntry) {
                    try {
                        poi.extractEmbeddedOfficeDoc((DirectoryEntry) entry, null,
                                xhtml, embeddedCnt);
                    } catch (TikaException e) {
                        // ignore parse errors from embedded documents
                    }
                }
            }
        }
    
        private class CustomAbstractPOIFSExtractor {
            private TikaConfig config = TikaConfig.getDefaultConfig();
    
            /**
             * Handle an office document that's embedded at the POIFS level
             */
            protected void extractEmbeddedOfficeDoc(
                    DirectoryEntry dir, String resourceName,
                    XHTMLContentHandler xhtml, int embeddedCnt)
                    throws IOException, SAXException, TikaException {
                if (dir.hasEntry("Package")) {
                    return;
                }
    
                // It's regular OLE2:
                POIFSDocumentType type = POIFSDocumentType.detectType(dir);
    
                try {
                    if (type == POIFSDocumentType.WORDDOCUMENT) {
                        FileOutputStream fos = new FileOutputStream(new File("test.doc"));
                        HWPFDocument document = new HWPFDocument((DirectoryNode) dir);
                        document.write(fos);
                        document.close();
                    } else if (type == POIFSDocumentType.POWERPOINT) {
                        FileOutputStream fos = new FileOutputStream(new File("test.ppt"));
                        HSLFSlideShowImpl document = new HSLFSlideShowImpl((DirectoryNode) dir);
                        document.write(fos);
                        document.close(); // After call this method, I cannot continue to extract embedded documents
                    }
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        }
    }

Code (markup):

- [extractEmbeddedOfficeDoc] method will write the stream of embedded documents to files.
When I call [HSLFSlideShowImpl.close()] method to close the stream of "test.ppt" document, I cannot continue to loop to extract the other embedded documents. The exception will be occurred.

Additional Information
- The exception was NOT occurred after I called [HWPFDocument.close()] method.

Now, I would like to fix this issue but I don't know the root cause of this issue. Please help me!

Thanks in advance.
