> We've encountered an issue in the interaction between the VolcanoPlanner and FilterableTable. Specifically, when the org.apache.calcite.util.trace.getPlannerTracer logger level is set to DEBUG, the isValid method within VolcanoPlanner throws an exception.
> *Steps to Reproduce:*
> # Set the logger level for org.apache.calcite.util.trace.getPlannerTracer to DEBUG.
> # Run an existing test that uses FilterableTable.
> $ ./gradlew :example:csv:test --tests "org.apache.calcite.test.CsvTest.testFilterableWhere"
> *Actual Behavior:*
> Running the above steps results in an AssertionError exception, which states:
> {code:java}
> FAILURE 1.1sec, org.apache.calcite.test.CsvTest > testFilterableWhere()
> java.lang.AssertionError: RelSubset [rel#42:RelSubset#2.ENUMERABLE.[]] has wrong best cost {130.0 rows, 246.0 cpu, 0.0 io}. Correct cost is {150.5 rows, 350.505 cpu, 0.0 io}
