Description

Calling JdbcTable.scan will result in a NullPointerException because inside JdbcTable.fieldClasses protoRowType is null.

This could easily be fixed by replacing

 final RelDataType rowType = requireNonNull(protoRowType, "protoRowType").apply(typeFactory);

with

 final RelDataType rowType = getRowType(typeFactory);
