Java Reflection Performance Analysis Using Different Java Development

Abstract

The reflection technique is used by programs that need to examine or modify the runtime behavior of applications in the Java Virtual Machine. This is a powerful instrument, but its use should bring some concerns related to performance overhead, security problems, exposing the private fields - which are not accessible through non-reflective code, losing benefits of compile-time type checking, reflective code being clumsy and verbose. This paper concentrates upon the performance overhead. Tests were made in order to analyze objects creation and method calls using primitive and reference arguments, both by direct and reflective invocation.
