Start by inspecting the linked-selection callback at WheelOptions.java:136 and the dispatch path through WheelView.java:349, using the ArrayList stack trace and version 4.1.8 as context. Reproduce the linked picker selection that triggers the exception and verify that the same interaction completes without an index-out-of-bounds crash.
