我负责维护java swing应用程序。它曾经在java 1.4上运行得非常好，但随着时间的推移，我们遇到了越来越多的JRE崩溃，这使我们升级到JRE 1.6，至少仍然由Sun维护。
使用JRE 1.6，我们现在遇到了一个不同类型的问题，在显示ECW图像文件的部分感谢JNI和本机dlls NCSEcw.dll，NCSUtil.dll和NCScnet.dll（由ERDAS生成，可以是在这里找到：http://www.erdas.com/Products/ERDASDownloads/tabid/192/CurrentID/2560/Default.aspx）。
大多数情况下，问题是冻结（可能是死锁）但是我们有一两次真正的JRE崩溃，我在下面复制了hs_err_pid消息。它并不出现在所有机器上，并且在相关机器上并不系统（尽管非常频繁）。大多数相关的机器似乎都运行Windows 2000 SP4，但它也出现在一些XP机器上，我找不到区分它们的标准。
JNI调用库的方式是否有区别，使其适用于1.4而不是1.6？我有点失落，谢谢你的任何线索。
