It seems it's related with JS strict mode. @atd is there any JS module involved in the execution? e.g a test library?

Not sure.. We are using https://github.com/prerender/prerender with the script at https://github.com/P2Pvalue/docker-prerender/blob/master/server.js

This seems to be one of the offending functions

I have searched arguments.callee.caller and cannot find the string in SwellRT code

Seems to be related with gwtproject/gwt#9132
