On the contrary -
normally the above code snippet will rarely be executed,
and so will normally not be inlined into the caller,
which makes it easier for hotspot to inline
the caller into its caller.  Separate cold code into
separate methods.

BTW, in case you try to benchmark this,
hotspot intrinsifies indexOf by default.
