Description

@VectorizedExpressions(value = { VectorStringRot13.class })

in a custom UDF Is ignored because the check for annotations happens after custom UDF detection.

The custom UDF codepath is on the fail-over track of annotation lookups, so the detection during validation of SEL is sufficient, instead of during expression creation.
