Detect memory leaks
- Use tools like JProbe, OptimizeIt etc to detect memory leaks.
- Use operating system process monitors like task manager on NT systems, ps, vmstat, iostat, netstat etc on UNIX systems.
- Write your own utility class with the help of totalMemory() and freeMemory() methods in the Java Runtime class.
- An even better approach than a utility class is using dynamic proxies or Aspect Oriented Programming (AOP) for pre and post memory recording where you have the control of activating memory measurement only when needed.
