Building robust and stable applications has always been a challenge. It is not uncommon that Java developers blindly rely on the garbage collector to clean up the heap memory. Even if memory leaks are avoided, a lot of out-of-memory errors can occur because new objects are created carelessly and then consume all the available memory. Heap memory is just one type of resource that is usually not addressed properly, other resources include CPU cycles, file handles, network connections, etc. In order to build robust and stable applications, the developer must deal with the management of these resources. This area is generally referred to as Resource Management.

In this session, an introduction into Resource Management is given by presenting a few design patterns, looking at some Java language features, and discussing a few selected examples.
The focus of the talk is to raise the awareness for the topic of Resource Management and to discuss various approaches.
