2010.4.2日晚-2010.4.3下午：

需要开发个小程序，用到了java 调用dll库。

dll我用delphi开发，其中涉及到处理xml文档.此dll在delphi开发环境下测试通过，可一在java环境中调用，则jvm崩溃.

为解决此问题

，从2010.4.2日下午一直干到2010.4.3日清晨4:00,未解决，在无比郁闷中沉沉睡去。

起床已是4.3日10:00点，隐约醒来，想着未解决的问题，继续郁闷，再睡不着，于是起床继续。

由java调用dll,程序又不报异常，直接由jvm崩溃，无法调试，导致我几乎崩溃。

在我崩溃前最后几秒(2010.4.3

13:49)，忽然灵光一闪，想到delphi操作xml文档，前后必加

CoInitialize(nil);

......

coUnInitialize();

是不是此原因呢？

再看delphi代码，果然，在调测dll用的例子中，我加了此两句，但在dll本身中未加此两句，所以用delphi本身的测试用例无问题，一到java中就出问题，于是把此两句加在dll操作xml相关位置。再次运行java,......pass,ok!!!!!

狂喜中！！！

反思开发过程：明知delphi操作xml需加CoInitialize(nil),coUnInitialize(),却又未充分认识它，导致时间浪费了整整一天，还茶不思饭不想。

jvm崩溃日志如下:
