Resource leak in zoom-sdk-android-5.7.6.1918

Meeting SDK Android
1

Description
While creating an Activity that extends MeetingActivity, in the super.onCreate() call there is a resource leak that is detected by Android’s StrictMode that has detectLeakedClosableObjects() enabled.

It appears there is a resource leak within us.zoom.androidlib.utils.ZmRomUtils.getSystemProperty where there is a FileInputStream that is opened but never closed.

Which Android Meeting SDK version?
zoom-sdk-android-5.7.6.1918

Screenshots
Decompiled us.zoom.androidlib.utils.ZmRomUtils class

public static String getSystemProperty(String key, String defValue) {
        if (key == null) {
            return defValue;
        } else {
            Properties properties = new Properties();

            try {
                properties.load(new FileInputStream(new File(Environment.getRootDirectory(), "build.prop")));
                return properties.getProperty(key, defValue);
            } catch (Exception var4) {
                ZMLog.e("ZmRomUtils", var4, "getSystemProperty exception, key=%s", new Object[]{key});
                return defValue;
            }
        }
    }
