JNA: __stdcall ESP corruption

当我试图通过JNA回调从C++应用程序获得通知时，我经常看到JVM崩溃。Native.setProtected没有帮助。原始回调声明是

typedef void (__stdcall *TRANS2QUIK_ORDER_STATUS_CALLBACK) (long nMode, DWORD dwTransID, double dNumber, LPCSTR ClassCode, LPCSTR SecCode, double dPrice, long nBalance, double dValue, long nIsSell, long nStatus, long nOrderDescriptor);

^^^这是不起作用的

我尝试了StdCallLibrary.StdCallback(应该可以工作)和简单回调，但都失败了。但在我编写了C++包装器之后，我只是从原始C++stdcall回调内部将JNA回调调用为cdecl，一切都开始顺利工作。

typedef void (*WRAPPED_ORDER_STATUS_CALLBACK) (double dNumber, double dPrice, long nBalance, double dValue, long nIsSell, long nStatus, long nOrderDescriptor);  
QUIKWRAP_API TRANS2QUIK_ORDER_STATUS_CALLBACK __stdcall wrapCallback(WRAPPED_ORDER_STATUS_CALLBACK);

这是在没有问题的情况下顺利工作的

问题是，这可能是专门针对该函数签名的JNA错误吗？因为我的代码中有另一个具有不同签名的stdcall回调，它运行得很好。

我为这个问题创建了一个独立的测试用例，请参阅下面的：java

import java.util.HashMap;
import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.NativeLong;
import com.sun.jna.Pointer;
import com.sun.jna.PointerType;
import com.sun.jna.platform.win32.WinDef;
import com.sun.jna.platform.win32.WinDef.DWORD;
import com.sun.jna.win32.StdCallLibrary;

public class JNATest {
interface TestCallback extends StdCallLibrary.StdCallCallback {
void testCallback(NativeLong nMode, WinDef.DWORD dwTransID, double dNumber, LPCSTR ClassCode, LPCSTR SecCode, double dPrice, NativeLong nBalance, double dValue, NativeLong nIsSell, NativeLong nStatus, NativeLong nOrderDescriptor);
}
interface JNADLL extends StdCallLibrary{
void testCallback(TestCallback cb);
}
public static class LPCSTR extends PointerType {
public LPCSTR(Pointer address) {
super(address);
}
public LPCSTR() {
super();
}
@Override
public String toString() {
return getPointer().getString(0);
}
};

/**
* @param args
*/
public static void main(String[] args) {
System.setProperty("jna.encoding", "Cp1251");
HashMap<String, Object> nameMapping = new HashMap<String, Object>();
nameMapping.put(Library.OPTION_FUNCTION_MAPPER, StdCallLibrary.FUNCTION_MAPPER);
nameMapping.put(Library.OPTION_CALLING_CONVENTION, StdCallLibrary.STDCALL_CONVENTION);
JNADLL JNADll = (JNADLL) Native.loadLibrary("QuikWrap", JNADLL.class, nameMapping);
TestCallback cb = new TestCallback() {
@Override
public void testCallback(NativeLong nMode, DWORD dwTransID,
double dNumber, JNATest.LPCSTR ClassCode, JNATest.LPCSTR SecCode,
double dPrice, NativeLong nBalance, double dValue,
NativeLong nIsSell, NativeLong nStatus, NativeLong nOrderDescriptor) {
System.out.println("testCallback  n" +
"  nMode: " + nMode + "n" +
"  dwTransID: " + dwTransID + "n" +
"  number: " + dNumber + "n" +
"  ClassCode: " + ClassCode + "n" +
"  SecCode: " + SecCode + "n" +
"  price: " + dPrice + "n" +
"  balance: " + nBalance + "n" +
"  value: " + dValue + "n" +
"  isSell: " + nIsSell + "n" +
"  status: " + nStatus + "n" +
"  orderDescriptor: " + nOrderDescriptor + "n");
}
};
JNADll.testCallback(cb);
}
}

c标题QuikWrap.h

#ifdef QUIKWRAP_EXPORTS
#define QUIKWRAP_API extern "C"__declspec(dllexport) 
#else
#define QUIKWRAP_API __declspec(dllimport)
#endif
typedef void (__stdcall *TRANS2QUIK_ORDER_STATUS_CALLBACK) (long nMode, DWORD dwTransID, double dNumber, LPCSTR ClassCode, LPCSTR SecCode, double dPrice, long nBalance, double dValue, long nIsSell, long nStatus, long nOrderDescriptor);
QUIKWRAP_API void __stdcall testCallback(TRANS2QUIK_ORDER_STATUS_CALLBACK cb);

c来源QuikWrap.pp

#include "stdafx.h"
#include "QuikWrap.h"
#include "stdio.h"
QUIKWRAP_API void __stdcall testCallback(TRANS2QUIK_ORDER_STATUS_CALLBACK cb){
cb(1, 2, 3, "Hi", "Bye", 4.0, 5, 6, 7, 8, 9);
cb(0, 2, 3, "Hi", "Bye", 4.0, 5, 6, 7, 8, 9);
return;
}

我得到的回调的唯一输出是

testCallback  
nMode: 1
dwTransID: 2
number: 3.0
ClassCode: Hi
SecCode: Bye
price: 4.0
balance: 5
value: 6.0
isSell: 7
status: 8
orderDescriptor: 9

然后退出时回调失败
