status behind JDK-8149738

Tue Apr 12 16:30:11 UTC 2016

Hi Guru,

I think I have isolated the problem ; it relates to GWT FlexTable (with
fixed column & row size) that is cleaned and refilled.
Tomorrow I'll build a clean GWT reproducer app and will send it to you.
I'll also do the exact same in pure html/js without GWT being involved.
