Re: [Htmlunit-user] htmlunit dies on page

[Ronald B. <rb...@rb...>]

Hi David,

at the moment we have some problems with our build environment. I had the same problems yesterday but this should be solved now.
Please use the latest snapshot (did a refresh some minutes before) and make sure you also refresh the core-js thing.
I guess this will solve your problem.
