Mickael Istria commented on JBIDE-19750:
----------------------------------------

Thanks for opening the jira.
I looked at it before the week-end and did not find the cause of the issue. Handles are typically consumed by graphics elements (color, images, fonts, shells...) and SWTBot doesn't create any graphic element, so it's very unlikely that this is related to SWTBot at all.
I tried to reproduce it locally, but it worked without issue.

I believe the main change might be the newer version of Central, using HTML now. so trying to hack the DefaultType of browser is a good idea.

> Wondering if ...
> a) passing through a different *swt.browser.DefaultType*, &/or 
> b) using a newer SWTBot (which works with Luna [1] now?)
