---------------------------------
> BitwiseCount / bit_count generated code for boolean inputs fails to compile
> ---------------------------------------------------------------------------
>
> Key: SPARK-48128
> URL: https://issues.apache.org/jira/browse/SPARK-48128
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0, 3.1.3, 3.2.4, 3.5.1, 3.3.4, 3.4.3
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.5.2, 3.4.4, 4.0.0
>
>
> If the `BitwiseCount` / `bit_count` expresison is applied to a boolean type
> column then then it will trigger codegen fallback to interpreted because the
> generated code contains invalid Java syntax, triggering errors like
> {code}
> java.util.concurrent.ExecutionException:
> org.codehaus.commons.compiler.CompileException: File 'generated.java', Line
> 41, Column 11: Failed to compile:
> org.codehaus.commons.compiler.CompileException: File 'generated.java', Line
> 41, Column 11: Unexpected token "if" in primary
> {code}
> This problem was masked because the QueryTest framework may not be fully
> exercising codegen paths (e.g. if constant folding occurs).
