A DESCRIPTION OF THE PROBLEM :
when JTextField is filled with text that contains:

right to left text like Arabic, Latin numbers and Latin text

then it only renders right if the complete text Fits inside the JTextField.

text we use to reproduce is:

other info: above text is just name of product inside an accounting software we created but our users have match more render failures as we could reproduce.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
create simple app with JTextField
with RIGHT_TO_LEFT component orientation
and set text:
صندوق ۴۰×۳۰ پایه دار وایرنگ میتر تک فاز
then run app and resize until text does not fit


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
fatal JTextField text render
ACTUAL -
JTextField renders text parts at unexpected locations

ERROR MESSAGES/STACK TRACES THAT OCCUR :
there is no error output the problem is just visual

REPRODUCIBILITY :
This bug can be reproduced always.
