About:
SJK (Swiss Java Knife) is a collection of command-line tools for analyzing and troubleshooting Java applications. It provides utilities for inspecting JVM internals, monitoring performance, and debugging issues in production environments. The toolset is particularly valuable for deep JVM diagnostics without requiring application restarts.

Key Features:

JVM process inspection and monitoring
Memory dump analysis and heap inspection
Thread dump analysis and deadlock detection
Low-overhead production-safe diagnostics
Command-line interface for automation

Use Cases:

Diagnosing memory leaks in production Java applications
Analyzing thread dumps to identify deadlocks and bottlenecks
Monitoring JVM health and performance metrics
Troubleshooting Java applications without restart

Alternatives:

jstack – Standard JDK tool, more basic output
jmap – Standard JDK tool, limited analysis features
VisualVM – GUI-based, requires X11/display, heavier resource usage
