WebP images turn green

[filex88]

Expected behavior

Actual behavior

Steps to reproduce the behavior

my code is:

Thumbnails.of(new ByteArrayInputStream(originalBytes))
					.size(targetWidth, targetHeight)
					.outputFormat("JPEG")
					.outputQuality(outputQuality)
					.scalingMode(ScalingMode.PROGRESSIVE_BILINEAR)
					.antialiasing(Antialiasing.ON)
					.useExifOrientation(true)
					.toOutputStream(outputStream);

i have also tried to set:

imageType(BufferedImage.TYPE_INT_ARGB)

or

imageType(BufferedImage.TYPE_INT_RGB)

and i already have ImageIO plugins imageio-core, imageio-jpeg, imageio-tiff, imageio-webp in my pom.

If I transform the image using other online tools before using it everything seems to work as it should.

The bug only appears with some webps and seems to be present also using other java image manipulation libraries that rely on ImageIO.

Has this issue been resolved?

I am using Thumbnailator version 0.4.8, and recently I have encountered an issue where images turn neon (bright colors) when generating thumbnails from uploaded images. This issue is not specific to certain images; even images that were processed correctly in the past are now affected.

For example, on September 11, when the issue occurred, images that had been processed without problems before September 10 also showed the same problem when re-uploaded on September 11.
