In this chapter, we have shown how to use the JRockit Mission Control Memory Leak Detector to detect and find the root cause for Java memory leaks. We have also discussed the advantages and disadvantages of the Memory Leak Detector in various use cases.

It has been demonstrated how the Memory Leak Detector can be used to detect even quite slow memory leaks. We have also shown how the Memory Leak Detector can be used in an interactive manner to quickly test particular operations in an application that may be prone to memory leaks.

We have explained how the Memory Leak Detector can also be used as an interactive general purpose heap analyzer to both find relationships between different types on the heap, as well as for inspecting the contents of any instance on the heap.

Finally, we showed how to troubleshoot the most common problems associated with using the tool.
