----------------------------------------
Resolution: Duplicate
Fix Version/s: 1.16.0
> Several TestConvertFunctions tests produce scalar replacement errors
> --------------------------------------------------------------------

> Key: DRILL-5161
> URL: https://issues.apache.org/jira/browse/DRILL-5161
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.8.0
> Reporter: Paul Rogers
> Priority: Minor
> Fix For: 1.16.0
>
>
> Run the unit test {{TestConvertFunctions}}. The {{testBinaryString}} test
> emits an ASM error (see below), though the test succeeds. In addition, the
> test {{testConvertFromConvertToInt}} also emits the error if the line to turn
> off scalar replacement is commented out (see test.)
> Another bug complains about the stack trace displayed when scalar replacement
> fails.
> This bug says that we should either not use scalar replacement if we can
> predict it will fail, or disable scalar replacement altogether so that we get
> clean tests. (Work elsewhere suggested that the Java compiler and runtime
> already to scalar replacement for us in the latest Java versions.)
> Stack trace:
