Trying to remember compiler implementation details this sounds reasonable and
is a bug (or an enhancement, actually ;-). Can someone file a bug?

Remi, I tried to reproduce your problem with jdk9 b44. It runs decently fast.
When did it start to regress?

yes, nashorn is fast enough but it can be faster if the JIT was not
doing something stupid.
When the VM inline fibo, because fibo is recursive, the recursive call
This could explain performance regressions we've seen on the
performance of heavily-recursive algorithms. I'll try to get an
assembly dump for fib in JRuby later today.

Hi guys,
I've found a bug in the interaction between the lambda form and inlining
algorithm,
basically if the inlining heuristic bailout because the method is
recursive and already inlined once,
instead to emit a code to do a direct call, it revert to do call to
linkStatic with the method
