Description

ExportWriter explicitly fails hard if you attempt to use it with any of the new Numeric Points based fields.

The current failures come from explicit if (fieldType instanceof TrieFooField) checks in ExportWriter.getFieldWriters – those could probably be replaced with instanceof FooValueFieldType (the numeric marker interfaces) or getNumericType() but i suspect in the multivalued case other problems will arise due to how ExportWriter dips into the guts of DocValues and assumes SortedSetDocValues
