JOverflow: Advanced Heap Analysis in Java Mission Control

Large Java applications tend to be memory-hungry. Most profiling tools tell users which data structures consume memory but don't tell whether that's good or bad or how to improve the situation. JOverflow, a recent extension to Java Mission Control, analyzes a heap dump automatically, looking for known bad memory usage patterns. It detects empty and underused collections, duplicated strings, unused data fields, and several other issues. What's more, for many of these problems, the tool can suggest a fix by analyzing application code together with the heap dump and thus save the developer hours of tedious and unrewarding work.
