在linux中，我得到了在Java生成的核心文件，它不能被打開jvisualvm，所以我想它翻譯成一個堆轉儲文件，但發生了一些錯誤：爲什麼`sun.jvm.hotspot.debugger.DebuggerException：無法打開二進制文件？
[[email protected]_test-1 game]$ jmap -J-d64 -dump:format=b,file=core.10255.dump java ./core.10255
Attaching to core ./core.10255 from executable java, please wait...
Error attaching to core file: cannot open binary file

如何解決它？
