The site is using an old version of maven-site-plugin which in turns depends (IIRC) on a version of Apache BCEL that does not know what to do with Java 8 and/or 9 byte codes.
I'm pretty sure that the current version of maven-site-plugin (3.7) has updated its dependency on BCEL to the latest where I updated the code to avoid this exception.
