【JVM】JNI最後一個問題 EXCEPTION_ACCESS_VIOLATION (0xc0000005)

MyEclipse中寫一個java程式，嘗試調用已經封裝好的dll，控制台出現如下錯誤：

# An unexpected error has been detected by HotSpot Virtual Machine:
#
#   EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x10005301, pid=708, tid=3224
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_13-b05 mixed mode, sharing)
# Problematic frame:
# C   [KDCCAvayaComm.dll+0x5301]
#
# An error report file with more information is saved as hs_err_pid708.log
#
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
#

hs_err_pid708.log記錄檔中有一堆log，也看不出什麼東東，反正是JVM出錯了，記得DLL拋出的異常是無法被JVM捕獲的，因此JVM就被強行停了下來。。崩潰

既然是DLL有異常，看來C++程式或JNI部分出錯，jni要調用的c++程式可以肯定是沒有問題的，那問題肯定出在jni的調用上，同時發現如果無參的介面則正常，調用帶了參數的方法就出現了問題，使用了try{}catch(...){}發現果然是jni代碼出錯，暈頭，問題還是出在一開始就感覺會出錯的地方！檢查下自己jni裡的方法調用或參數傳遞有沒有問題！搞了幾年java，突然要弄C++還真頭大，估計類似的出了問題也都很頭大吧！

不過一開始在網上搜尋了半天
EXCEPTION_ACCESS_VIOLATION (0xc0000005) 既然沒有可取的答案，只找到這句話（DLL拋出的異常是無法被JVM捕獲的，因此JVM就被強行停了下來。。）感覺最有用，所以有第一次使用JNI的如果遇到這個問題可以直接看自己的JNI部分的代碼是否正確，當然還有更權威的資料，如果你想查閱的話！
