The error message of the exception that is thrown by `ImageStorage` when attempting to load an unsupported image type is: "No loader for image data". If you're encountering a different exception, maybe it originates from somewhere else.
That being said, you're right that OpenJFX doesn't care about file extensions and only checks file signatures. For both HEIC and AVIF files, that's "ftyp" followed by a `major_brand` identifier. Maybe you're encountering files with different kinds of `major_brand`? Note that image loaders are an implementation detail of OpenJFX and not public API, which means that the classes could change at any time without notice.
