Java x64的jna活动窗口进程名称

我获得了x86程序（在C:\ProgramFiles（x86）中）所需的所有信息，下面的语句没有任何问题。但对于x64，activ窗口进程名称的结果为空。是否可以检测带有jna的x64处理器的活动窗口进程名（.exe路径）

• 用于x64的Eclipse Luna
• Windows 8 pro x64
• JRE8 x64
• jna 4.1.0

如果我将我的项目导出到runnable jar，我就可以毫无问题地获得x86和x64软件的所有信息。 如果我从Eclipse运行项目，上述问题只会影响on，因为它需要一个指向32位内存的指针。你给它一个指向指针的指针，它是32位还是64位取决于你的平台。然后将一个64位的值传递给，这需要一个32位的值。
