Description

"Uncaught TypeError: M is undefined"

The JS is minified, so the snippet is here:

else{setTimeout(N.open,H*R++);}};};M.onerror=function(T){var U=F[P];for(var S=U.length-1;S>=0;S--){var V=U[S];G[V]["onerror"]

I compared the code and found it matches this section:

https://github.com/apache/myfaces/commit/712b6c9ddddd3425ad2b58ae3aeaf0277755ecc5#diff-1922615a79308869d0efa08412e8e9bbd804958f62de191eaa9b576aa993b5d6R339

 So I think socket.onerror is in the wrong block?
