| 27 | TDA (Thread Dump Analyzer) for Java is a powerful yet lightweight Swing GUI and **MCP Server** for analyzing Thread Dumps and Heap |
| 28 | Information generated by the Java VM. It is designed to assist in diagnosing performance issues, deadlocks, and |
| 29 | memory problems in Java applications. With its MCP capabilities, TDA can be seamlessly integrated into AI-powered |
| 30 | development workflows. |
| 31 | |
| 32 | TDA supports Java 1.4.x through Java 21+, including specialized support for **Virtual Threads** (Java 19+) and **JSON-based thread dumps** |
| 33 | (Java 21+, experimental). |

| 52 | ## 🚀 Key Features |
| 53 | |
| 54 | * **Comprehensive Thread Dump Parsing**: Parse multiple thread dumps from log files and display them in an intuitive tree structure. |
| 55 | * **Virtual Threads Support**: Analyze virtual thread states, pinning issues, and carrier thread relationships. |
| 56 | * **Statistical Analysis**: Detailed statistics about thread states, monitors, and waiting/locking threads. |
| 57 | * **Long-Running Thread Detection**: Identify threads that persist across multiple dumps, helping find "hung" or inefficient code. |
| 58 | * **Deadlock Detection**: Automatic identification of deadlocks with detailed monitor information. |
| 59 | * **JSON-based Thread Dumps**: Support for parsing JSON-formatted thread dumps created with `jcmd <pid> Thread.dump_to_file -format=json <file>`. |
| 60 | *Note: JSON dumps currently provide basic information (name, tid, stack trace) but lack details like thread states or native IDs. For comprehensive analysis, textual dumps are recommended.* |
| 61 | * **Class Histogram Analysis**: Integrated analysis of heap objects (via `-XX:+PrintClassHistogram`). |
| 62 | * **Flexible Filtering & Categorization**: Use custom filters and categories to manage large numbers of threads. |
| 63 | * **Model Context Protocol (MCP) Support**: He |
