A method or constructor may be annotated as "force inline" if the standard inlining metrics are to be ignored when the HotSpot VM inlines the method or constructor.

This annotation must be used sparingly. It is useful when the only reasonable alternative is to bind the name of a specific method or constructor into the HotSpot VM for special handling by the inlining policy. This annotation must not be relied on as an alternative to avoid tuning the VM's inlining policy. In a few cases, it may act as a temporary workaround until the profiling and inlining performed by the HotSpot VM is sufficiently improved.
