How would you find a memory leak in a production Java application (OutOfMemoryError only in production, or memory climbing until the JVM crashes)?
Tests whether you'd capture a heap dump near the crash point and analyze dominator trees/retained size in a tool like Eclipse MAT to find what's holding references, rather than guessing based on code review alone -- production-only leaks often depend on data volume or traffic patterns local testing never reaches.
