maven-site-plugin unhappy with jdk 1.8?

I have recently udated my jdk from 1.7 to 1.8.
Now I am having problems with the maven-site-plugin which fails with the
error:

Error during page generation: Error rendering Maven report:
Unsupported targetJdk value '1.8'.

Is there a way to specify a different targetJdk value to the plugin?
Is there a plan to update the plugin to accommodate jdk 1.8?

Thanks,
Andy
