return 1*1 pixel image in response play scala

i need to return a same dummy image of 1*1 pixel in every response. I am using bufferArray to do this, my code snipet is as follow : 

val image: BufferedImage = ImageIO.read(new File("public/images/dummy.png"));
val baos: ByteArrayOutputStream = new ByteArrayOutputStream();
ImageIO.write(image, "png", baos);

Ok(baos.toByteArray).as("image/png")

after some time server throws error, java.io.excp too many files open. please help, is there any another way to do this ?

i have put that imagebuffer part in another object (i.e. object abc{}) and using it as abc.baos. but the error is same.

You can just use:

Ok.sendFile(new File("public/images/dummy.png"))

You should be able to just serve the file as a response. Play has a responsewriter for files, so no need for the ByteArrayBuffer. If you do so Play should also close the file for you after it was being served.
