Tail Call Optimization in Java: An ASM Bytecode Manipulation Approach

This article presents a neat way to implement tail call optimization in Java using bytecode manipulation with ASM. Tail recursion, where the recursive call is the last operation, can be significantly optimized by avoiding the creation of new stack frames for each call. The article details method call mechanics, the structure of tail recursion, and the usage of the ASM library. JMH benchmarks demonstrate performance improvements, especially with a higher number of recursive calls, showcasing the effectiveness of this optimization technique.
