wmic process empty executablepath

Question

Why do some processes from wmic process get name, commandline, processid, executablePath not display a value for ExecutablePath ?

But I can find it in taskmanager ?

Is there any way to get executable path from wmic ?

Thank you all, especially to @Eryk Sun, here is my quite simple solution for others who will contend with same problem.

import com.sun.jna.platform;

String getExPath(int pid) {
        Kernel32 kernel32 = Kernel32.INSTANCE;
        WinNT.HANDLE hProcess = kernel32.OpenProcess(WinNT.PROCESS_QUERY_LIMITED_INFORMATION, false, pid);
        char buffer[] = new char[1024];
        IntByReference size = new IntByReference(buffer.length);
        kernel32.QueryFullProcessImageName(hProcess, 0, buffer, size);
        return new String(buffer).trim();
}

I was looking for similar method for obtain a commandline of process but i was not sucessfull. I appreciate an advice.
