Description

java.lang.ClassCastException: [B cannot be cast to java.lang.String
	at org.apache.calcite.avatica.util.AbstractCursor$StringAccessor.getString(AbstractCursor.java:726)
	at org.apache.calcite.avatica.AvaticaResultSet.getString(AvaticaResultSet.java:233)
	at sqlline.Rows$Row.<init>(Rows.java:183)
	at sqlline.IncrementalRows.hasNext(IncrementalRows.java:63)
	at sqlline.TableOutputFormat.print(TableOutputFormat.java:33)
	at sqlline.SqlLine.print(SqlLine.java:1653)
	at sqlline.Commands.execute(Commands.java:833)
	at sqlline.Commands.sql(Commands.java:732)
	at sqlline.SqlLine.dispatch(SqlLine.java:808)
	at sqlline.SqlLine.begin(SqlLine.java:681)
	at sqlline.SqlLine.start(SqlLine.java:398)
	at sqlline.SqlLine.main(SqlLine.java:292)

JSON encoding doesn't have this issue. The StringAccessor (actually a BinaryFromStringAccessor) expects to get back a String as the object but it gets a byte[].
