and line 97 of FennecNativeDriver is this:

mRegisterGEL = mGas.getMethod("registerGeckoEventListener", parameters);

For some reason the method isn't being found even though it exists.
This turned a whole bunch of (talos) jobs on a recent push red... as well as robocop units orange.

We either need to backout its cause asap or fix it, imo.

Could this be rlalted to Bug 765766?

Hasn't this been fixed by the new patch on bug 687267?
Well it was fixed by the backout cset in comment 15, and the new patch on bug 687267 didn't reintroduce it.

Why does this affect 16 and 15? The patch that introduced it was never uplifted, AFAIK.

I though it was introduced by bug 687267.
It was introduced by cset 8571114112b2, which was backed out before being uplifted. bug 687267 was fixed with a different patch that didn't have this problem.

Also I checked the tbpl pages for aurora and beta, and the robocop tests are passing fine, so this bug definitely doesn't affect those branches.
