Android WifiManager getConnectionInfo requires CHANGE_WIFI_STATE?

问题

I'm getting a user report on an error about missing the CHANGE_WIFI_STATE permission:

Error:

java.lang.SecurityException: WifiService: Neither user 10137 nor current process has android.permission.CHANGE_WIFI_STATE.
    at android.net.wifi.WifiManager.getConnectionInfo(WifiManager.java:642) 

This is the code block:

WifiManager wifiMan = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (wifiMan != null) {
    WifiInfo wifiInfo = wifiMan.getConnectionInfo();

I thought this only required ACCESS_WIFI_STATE, since I'm not doing any enabling/disabling of wifi? Haven't been able to replicate in testing.
