Basically, this was caused by an incompatible ffi version. We use FFI 0.1.3, and we will update to ffi 1.0 for one of the next releases. Until then other plugins that do not use 0.1.3 will not work together with the HERE SDK. This is a general problem with FFI.
With HERE SDK 4.6.5 this error was made more explicit.
