Empty JPEG2000 image after upgrading from 10.2.0 to 10.3.0 #7945
Description
What did you do?
I want to load a JPEG2000 image from raw data into Pillow for further processing. After upgrading from 10.2.0 to 10.3.0, this broke for a specific image.
What did you expect to happen?
The image is being loaded as before.
What actually happened?
The image is not being loaded correctly and just empty.
