Priority: P2 Bug ID: 53613 Assignee: dev@poi.apache.org Summary: org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeEx ception: Rule M2.4 exception : this error should NEVER happen Severity: normal Classification: Unclassified Reporter: jbatche...@mutualnc.com Hardware: PC Status: NEW Version: 3.8 Component: XSSF Product: POI Created attachment 29122 --> https://issues.apache.org/bugzilla/attachment.cgi?id=29122&action=edit This is the spreadsheet that my program tries to open and close. The program corrupts the spreadsheet when run. I experience this exception being thrown: org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Rule M2.4 exception : this error should NEVER happen, if so please send a mail to the developers team, thanks ! This is example code that triggers the error. The statement wb.write(fileOut); specifically seems to be the culprit. package areacontrol; public class AreaControl_3 { public static void main(String[] args) { String filename = "C:\\java\\values.xlsx"; try{ org.apache.poi.openxml4j.opc.OPCPackage opc = org.apache.poi.openxml4j.opc.OPCPackage.open(filename); org.apache.poi.xssf.usermodel.XSSFWorkbook wb = new org.apache.poi.xssf.usermodel.XSSFWorkbook(opc); opc.close(); java.io.FileOutputStream fileOut = new java.io.FileOutputStream(filename); wb.write(fileOut); fileOut.close(); }catch(Exception e){ System.out.println(e); } } } This code does not generate the exception: package areacontrol; public class AreaControl_3_1 { public static void main(String[] args) { String filename = "C:\\java\\values.xlsx"; try{ java.io.FileInputStream fis = new java.io.FileInputStream(filename); org.apache.poi.xssf.usermodel.XSSFWorkbook wb = new org.apache.poi.xssf.usermodel.XSSFWorkbook(fis); fis.close(); java.io.FileOutputStream fileOut = new java.io.FileOutputStream(filename); wb.write(fileOut); fileOut.close(); }catch(Exception e){ System.out.println(e); } } } I have attached the spreadsheet. -- 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
