org.apache.xmlgraphics.image.loader.ImageSessionContext
This interface is used to tell the cache which images are used by a session (in FOP that would be a rendering run). Images access within a session get a hard reference so they cannot be discarded. That could increase memory usage but helps with performance because the images don't get unloaded between layout and rendering which would mean that they have to be reloaded.
