崩溃发生在Java虚拟机之外的本地代码错误，同时编辑Excel文件
我正在尝试使用Apache POI和OPCPackage来编辑excel文件，而且由于某些奇怪的原因，这并不适合我。 这里是代码片段：
File file = new File(basePath, fileName); int currentColNum=0, currentRowNum=0; OPCPackage pkg = null; Workbook wb = null; if(file.exists()) pkg = OPCPackage.open(file); wb = new XSSFWorkbook(pkg); else wb = new XSSFWorkbook(); Sheet sheet = wb.getSheet(sheetName); if(sheet==null) sheet = wb.createSheet(sheetName); else currentRowNum = lastWrittenRowCol.get(sheetName).getLeft(); for(Entry<?,?> entry : map.entrySet()) { //some code. This code uses functions like sheet.createRow() etc. } FileOutputStream out = new FileOutputStream(file); System.out.println("before write.out"); //Printed/ wb.write(out); System.out.println("last statement"); //Not printed. out.close(); if(pkg!=null) pkg.close();
我得到以下错误：
# # A fatal error has been detected by the Java Runtime Environment: # # SIGBUS (0x7) at pc=0x00002b517248dae2, pid=14557, tid=47628802967872 # # JRE version: 7.0_25-b15 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.25-b01 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libzip.so+0x4ae2] newEntry+0x62 # # Failed to write core dump.

这是来自日志的内存信息：

我正在使用Eclipse。 程序运行参数-Xms512m -Xmx2048m 。 wb.write(out)存在一些问题，因为在该行之前的语句被打印，而下一个不是。 （我知道我应该使用debugging器，但是我不知道如何将它插入到我们的构build系统中的eclipse中）。 任何帮助感激！
由于XSSF操作Open XML格式，编写它需要对档案（zip）进行操作.Jzlib中存在错误。
请检查此修复JVM在libzip.so崩溃
我希望这可以帮助！
