Description

After a full fresh install of NB12.6 and trying to run with Azul Open JDK 1.8 312, there are several ClassNotFoundExceptions in the logs. It seems that NB looks for missing methods that make NB not longer properly. For example, it is no longer possible to properly format Java sources files due to a java/nio/CharBuffer method missing.

Is NB platform supposed to no longer work with Java 8?
