--------------- T H R E A D ---------------
原因:
Minidump是Windows上的程式crash的時候可以寫出的一種小型crash dump,會記錄導致crash的錯誤的摘要資訊,以便開發人員可以事後調查crash的原因。HotSpot VM在非server版的(也就是client版的)Windows上選擇預設不寫出minidump。
解決:
要讓HotSpot VM在client版Windows上寫出minidump,請指定 -XX:+CreateMinidumpOnCrash,這樣HotSpot VM在crash時就會調用Windows的MiniDumpWriteDump()函數寫出minidump。
