The CheckpointListener in the spec sounds like the methods are to be executed around the act of Checkpointing itself, instead of around the chunk of items. Spring Batch's ChunkListener's beforeChunk is executed prior to any items being processed and afterChunk is executed once all of them within the chunk have been completed.

I think the issue is only terminology. We have a blending of WebSphere and Spring wording. WebSphere uses the term "checkpoint" not only to cannote the actual act of writing the checkpoint, but also extends the term to refer to the items processed since the last time a checkpoint was taken. Hence checkpoint = chunk. I will look to clarify the language in the next spec draft. I am planning a flow diagram, which will help.

After further review, I realize there is a distinction between before/after chunk and before/after checkpoint. I revised the spec: 1) renamed CheckpointListener to ChunkListener 2) added beforeChunk/afterChunk method annotations 3) kept beforeCheckpoint/afterCheckpoint method annotations
