SUGGESTED FIX

Link sun.dyn.MethodHandleImpl class before generating the method handle adapters.  This ensures that the required c2i-adapter exists.

Part of the backtrace is:

<snip>

The failing methodOop is:

sun.dyn.MethodHandleImpl::raiseException

Since 7007377 during method handles adapter generation the adapters for sun.dyn.MethodHandleImpl::raiseException are also generated.  Later when the Rewriter wants to link the method the adapter entry already exists and the assert triggers.
