Bug ID: 68652 Summary: Creating XSSFWorkbook with path argument in constructor cause unexpected and not transparent source file modification. Product: POI Version: 5.2.3-FINAL Hardware: All OS: All Status: NEW Severity: normal Priority: P2 Component: XSSF Assignee: dev@poi.apache.org Reporter: drozhdz...@gmail.com Target Milestone: --- I am using XSSFWorkbook for parsing xlsx files (only reading data). For XSSFWorkbook creation I am using following constructor: XSSFWorkbook(String path) After testing my solution I discovered that there is some unexpected non-transparent undesired behavior: after closing workbook (I am using try with resources construction) source file is rewritten updated by its compressed version; this is unexpected for me since file is opened only for reading data. Using following workaround changes this behavior: static Workbook getWorkbook(String fullFileName) throws IOException { try { return new XSSFWorkbook(OPCPackage.open(fullFileName, PackageAccess.READ)); } catch (InvalidFormatException e) { throw new IOException(e.toString(), e); } } Library version used in my solution is 5.2.5 (not present in version dropdown). -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
