 ## Goal
 
 The project provides a collection of `System prompts` for Java Enterprise development that help software engineers in their daily programming work.
-The [available System prompts for Java](./CURSOR-RULES-JAVA.md) cover aspects like `Build system based on Maven`, `Design`, `Coding`, `Testing`, `Refactoring & JMH Benchmarking`, `Performance testing with JMeter`, `Profiling with Async profiler/JDK tools`, `Documentation` & `Diagrams`.

+# Spring Boot Memory Leak Demo
+
+## Controller Configuration
+
+This demo includes two controllers that can be conditionally enabled based on the `coco` property:
+
+- **CocoController**: Contains intentional memory leaks for demonstration purposes
+- **WithoutCocoController**: Proper implementation with resource management
+
+### Configuration Options
+
+Set the `coco` property in your application properties:
+
+```properties
+# Enable CocoController (with memory leaks for demo purposes)
+coco=true
+
+# Enable WithoutCocoController (proper resource management)
+coco=false
+```
+
+### Profile-Specific Configuration
+
+- **Default profile** (`application.properties`): `coco=true` (enables CocoController)
+- **Virtual Threads profile** (`application-vt.properties`): `coco=false` (enables WithoutCocoController)
+
+### Usage Examples
+
+```bash
+# Run with CocoController (memory leaks)
+./mvnw spring-boot:run
+
+# Run with WithoutCocoController (proper resource management)
+./mvnw spring-boot:run -Dspring.profiles.active=vt
+
+# Override property at runtime
+./mvnw spring-boot:run -Dcoco=false
+```
+
+## Essential Maven Goals:

+## Enhanced Profiling with Java 25 JFR Support
+
+The profiler script has been enhanced with comprehensive Java 25 JFR support. See `profiler/JAVA25-JFR-FEATURES.md` for details.
+
+### New Profiling Options (v4.2):
+- **Option 17**: Enhanced JFR Memory Profiling (Java 21+)
+- **Option 18**: Java 25 CPU-Time Profiling (Linux only)
+- **Option 19**: Java 25 Method Tracing
+- **Option 20**: Advanced JFR with Custom Events
+- **Option 21**: JFR Memory Leak Analysis with TLAB tracking
+
+### Usage:
+```bash
+# Run the enhanced profiler
+./profiler/scripts/profile-java-process.sh
+
+# Start the application first
+./mvnw spring-boot:run
+
+# Then in another terminal, run the profiler and select from 21 options
+```
+
+### Cursor Rules Integration:
 My Java application has performance issues - help me set up comprehensive profiling process using @151-java-profiling-detect.md and use the location examples/spring-boot-memory-leak-demo/profiler
 
 Analyze the results located in examples/spring-boot-memory-leak-demo/profiler and use the cursor rule @152-java-profiling-analyze
