Hippo4j is a dynamic thread pool management toolkit for Java applications. It provides a centralized platform for monitoring, adjusting, and extending thread pool behavior across distributed systems without requiring application restarts. The project distinguishes itself through runtime thread pool resizing, allowing live modification of core size, maximum size, queue capacity, and rejection policy. It includes an approval-based change workflow that requires administrative authorization before parameter modifications take effect in production. Hippo4j also exposes container thread pools for T
jvm-sandbox is a bytecode instrumentation framework and plugin container for the Java Virtual Machine. It acts as a runtime application modifier that enables the injection and modification of bytecode in a running process without requiring an application restart or changes to the original source code. The system provides a non-invasive aspect-oriented programming framework to intercept method execution and alter behavior in live processes. It functions as an isolated environment for functional modules, employing a custom class loader hierarchy to prevent dependency conflicts between plugins a
btrace is a JVM dynamic tracing tool and performance profiler used for injecting safe instrumentation scripts into a running Java Virtual Machine without requiring a process restart. It functions as a Java agent framework and a Model Context Protocol server, exposing JVM diagnostic operations and tracing tools to large language models and AI assistants. The project distinguishes itself by enabling real-time code injection and bytecode-level instrumentation via a secure binary protocol. It ensures production stability through a static safety analysis engine that blocks unstable code patterns,
This project is a Gradle plugin designed to facilitate aspect-oriented programming within Android applications. It functions as a build-time tool that intercepts method calls to inject cross-cutting logic, allowing developers to centralize concerns such as logging, security, or performance monitoring without modifying individual source files. The plugin distinguishes itself by its ability to perform binary dependency weaving, which applies instrumentation across both local source code and external library formats like JARs and AARs. By utilizing the Gradle Transform API, it integrates directl
