New question #258736 on Sikuli:
https://answers.launchpad.net/sikuli/+question/258736

After discovering some unexpected behaviour in my Script; I decided to run a test to pin it down.
I discovered the following:

Match m = Screen.getScreen(0).exists("pathtoimage",10)
System.out.println(null == m);
Match n = Screen.getScreen(0).exists(ImageIO.read(new File("pathtoimage")),10)
System.out.println(null == n);

The first statement uses a String path to the image,
the third statement uses a BufferedImage object (which it creates from the file which is found by the very same string from before.)

the second and the fourth statement are both expected to print false, as the image in question is open on the main screen;
however the output is the following:

Dez 07, 2014 10:47:03 AM java.util.prefs.WindowsPreferences <init>
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
2
false
[error] Region.exists: seems that imagefile could not be found on disk
true

The reason why I work with BufferedImage objects is to reduce the Workload each time I search for a Image that was searched for previously. (I have 32 gbytes of ram that can be filled with all the images it wants, but I don't want the script to acces the harddisk if it can be avoided)

Does anyone know how this situation arises?
I also understand German
