java crach 日誌解析

在java開發中，或許會出現以下錯誤，這種錯誤大多出如今開發中涉及本地代碼的地方。

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000057441b5f, pid=9272, tid=0x0000000000004534
#           信號名稱             信號碼         程序計數器的值       進程號     線程號
# JRE version: Java(TM) SE Runtime Environment (8.0_171-b11) (build 1.8.0_171-b11)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.171-b11 mixed mode windows-amd64 compressed oops)
# Problematic frame:
# V  [jvm.dll+0xc1b5f]
  問題幀信息（和pc等價，但表達方式爲 本地庫+偏移量）
#
# Failed to write core dump. Minidumps are not enabled by default on client versions of Windows
#
# If you would like to submit a bug report, please visit:
#   http://bugreport.java.com/bugreport/crash.jsp
#

這種錯誤主要來源：

1. 自定義本地方法有誤，有不合邏輯，很大多是參數傳遞有誤（或者參數自己有誤）
2. 虛擬機內存問題，根據日誌進行GC分析，合理配置內存參數
3. 虛擬機自己錯誤（可能性很小）
