Here is the error:

Thank you for the detailed version information. I am currently on vacation for this week, but will check it out once I am back at my workstation.

It looks like a generics specificity disagreement between your new version of java and the older version I had used last time I built collide. Most likely, capturing the value of Elements.asJsElement(element) into a local variable should help the compiler disambiguate which type you mean to use.
