Apologies for delay. Didn't have time to look into it.
- Compilation errors, due to moving job params from the instance to the execution - no big deal
- Was getting runtime errors from Spring Batch Admin for pre 2.2. jobs, but adding BATCH_JOB_EXECUTION_PARAMS resolved this, - not really an issue.
- Need to refactor an internal component - can't go into too much detail for confidentiality reasons - due to job params relocating to execution. Need to locate Spring Batch meta-data by date range for a cleanup task. A day or two's work - but will need to be planned in for us to move to 2.2
So as said, it isn't a "huge" change.
Assume the Spring Batch Admin 1.3 release will align with 2.2.
