I did actually hit a bug today where the when value was being evaluated even though the condition was false. I wasn't able to find the exact root cause yet but turning off subexpression elimination fixed the issue. It was basically `when(col.rlike(...), udf(col))`, but more complex on both sides so somehow the UDF was getting subexpression eval'd early and failed because it didn't match the regular expression -- This is an automated message from the Apache Git Service.
