Understanding Java Object Behavior, Method Area, and Dynamic Tracing with Instrumentation, BTrace, and Arthas

This article explains how Java objects store attributes and shared behavior, describes the JVM method area where method bytecode resides, and demonstrates runtime bytecode manipulation using java.lang.instrument.Instrumentation, BTrace scripts, and the Arthas diagnostic tool to solve real‑world debugging problems.

Dynamic‑Tracing Based Memory‑Leak (Growth) Analysis for MySQL‑Proxy in TDSQL

Using lightweight dynamic‑tracing tools that record allocator calls and page‑fault events, the authors diagnose a production MySQL‑proxy memory leak in TDSQL, generate focused flame‑graphs with custom memstacks and pgfaultstacks, and demonstrate a fast, source‑independent alternative to gdb or Valgrind.
