> {{RelBuilder}} creation fails with error 'No suitable driver found for jdbc:calcite:'. We should not need to initialize a "jdbc:calcite" driver to make a {{RelBuilder}}.
> We just tracked down a nasty issue with Calcite being shaded as a dependency in our code that could cause a stack like
>  
> {noformat}
> No suitable driver found for jdbc:calcite: 
> org/apache/calcite/tools/Frameworks.java:184:in withPrepare 
> org/apache/calcite/tools/RelBuilder.java:225:in create
> {noformat}
> when calling {{RelBuilder.create}}.
> Our fault ultimately, but [~julianhyde] pointed out that Calcite really shouldn't be trying to make a JDBC connection here.
