Dennis Lundberg commented on WHISKER-13:
----------------------------------------

Now that we have a Jenkins job that builds the site using the latest Java 8, another problem with the site build has been found. In the log it looks like this:

This is most likely due to ASM, which is a common problem with Java 8.
