Error reading TLK Index on alpha dev

 The following error’s being thrown on line 518 of BinaryRecordReader

You can recreate it with the following java code:

HPCCFile file = new HPCCFile("thor_data400::key::insuranceheader_xlink::20210723_java::did::word::fname",
        https://alpha_dev_thor_esp.risk.regn.net:18010/ , "userame","password!");
FieldDef rm=file.getRecordDefinition();

The problem occurs when parsing the second field (initialchar) of the 401^st^ record, consistently. When I debug into it, the first field (fname) for this record is showing up bizarrely as “ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ”.

This issue is impacting the MCI product's development which depends on streaming these indexes out of alpha-dev; they will need it resolved before they can continue work.
