JNA：java.lang.Error：无效的内存访问Fortran DLL

Question

JNA的新手，但获取无效的内存访问尝试链接Fortran DLL。

的Fortran代码：

FUNCTION OpenFile(FileName,LenFileName) RESULT(Stat) 
INTEGER,INTENT(IN) :: LenFileName 
CHARACTER(LEN=LenFileName),INTENT(IN) :: FileName 
INTEGER :: Stat 

!Set the level of messaging to error and warning messages only 
CALL ZSET('MLEVEL','',0) 

!Set an unconnected unit number for the file 
CALL ZSET('UNIT','',1111) 

!Open file 
CALL ZOPEN(IFLTAB(:,iOpenFiles+1),FileName,Stat) 

iOpenFiles    = iOpenFiles + 1 
cFileNames(iOpenFiles) = FileName 
END FUNCTION OpenFile 

接口：

public interface test extends com.sun.jna.Library { 
    test reader = (test) Native.loadLibrary("test.dll", test.class); 

    int OpenFile(String FileName, int LenFileName); 
} 

并使用此调用它：

int ret = test.reader.OpenFile(fileName, fileName.length());  

错误林recieving

Exception in thread "main" java.lang.Error: Invalid memory access
