null pointer exception on Jasper studio with barcode (eclipse plugin)

1

When putting two or more barcode in a report, you'll get random null pointer exception.

It's random, but easy to reproduce: simply put a "codabar" barcode with barcode4j, then add another "codabar" and switch from an item to another

here a stak trace from eclipse:
