以上是运行时Jvm产生的错误日志
因为java可以通过jni调用c＋＋或者C，而它们又可以调用汇编语言，所以java应该可以通过这一系列的调用达到调用汇编的目的，
java语言的部分就不用说了，我的cpp实现如下：
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
#include"AsmTest.h"
#include"iostream.h"
JNIEXPORT void JNICALL Java_AsmTest_HelloWorld
(JNIEnv *, jobject){
char mess[]="hello world!";
_asm{
push edx
push eax
lea edx,mess
mov eax,00000900h;
int 21h;
pop eax
pop edx
}
}
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
开始没有对对edx，eax保护时也出现上边的错误日志，于是怀疑是用c++实现输出用到的寄存器破坏了jvm的运行，可以加上保护之后还是一样。
由于c语言的一些基本函数也是用汇编实现的，理论上来说直接在c＋＋里嵌入汇编，然后由java调用也是可以实现的，不知道什么原因不能实现
