    Status: Open => Answered

RaiMan proposed the following answer:
URL path1 = "Sikuli/test1.png";

... is not valid Java: a String cannot be converted to an URL

Finder() and Finder.find() accept valid path strings.
Valid means, that the image file can be loaded from the given path: absolute paths always work if valid.

Relative paths can only be evaluated against a valid ImagePath.

In your case it would give:
String path1 = "Sikuli/test1.png";
Finder finder = new Finder(path1);

[error] ImagePath: find: not in ImagePath: Sikuli/test1.png
[debug] ImagePath: BundlePath: --- not set ---
[error] java.lang.NullPointerException: Cannot invoke "java.awt.image.BufferedImage.getType()" because "bImg" is null

I do not know, where your folder "Sikuli" is in your file system, but something like this would help:
ImagePath.setBundlePath("/..../somewhere/Sikuli/");

and then:
String path1 = "test1.png";
String path2 = "test2.png";
Finder finder = new Finder(path1);
finder.find(path2);

if (finder.hasNext()) {
System.out.println("found");
}

would work.

I recommend to use SikuliX 2.0.5 and Java 8+ 64-Bit, because earlier
versions are no longer supported in case of problems.
