UnsupportOperationException when recording

Gatling (Open-Source)

Hi,
I get UnsupportedOperationException when I try to record a scenario. Everything works fine until I click on a button. The button has a javascript onclick listener that should open a menu. Then I get this exception:

Do you know what I’m doing wrong?

Thanks,

Have been browsing for 15 minutes on various big websites (merchant, banking…), with tons of resources and javascript, and couldn’t reproduce.
I’m afraid I won’t be able to do anything without a test case, sorry…

It works after updating my JVM and rebooting.

My apologies for this non-issue and thanks for your quick response.

No problem. I’d rather have this kind of false issues than real ones…

Thanks for letting us know.
Cheers,

Stéphane
