-fresh File Geodatabase created using ArcCatalog 10.1;
-one feature class in FGDB;
-one table in the same FGDB;
-make a feature layer from feature class;
-make a table view from table;
-add join using feature layer and tableview as inputs, KEEP_COMMON;
-execute copyfeatures to write new featureclass into the same FGDB and preserve joined data in output;

This works (sometimes) in modelbuilder but doesnt work in a standalone python script. It doesn't seem to matter if join columns are indexed or not.

Is this a known defect and if so, is it going to be fixed soon as I have dozens of scripts that use this workflow that work just fine in earlier releases?
