Introduces jcapslock-agent module for runtime capability detection and policy enforcement: - CapslockAgent: Java agent entry point, instruments JDK classes at startup - CapabilityTransformer: ASM-based bytecode transformer for capability methods - PolicyChecker: Stack inspection and policy enforcement with YAML config support Features: - Log-only mode: monitors capability usage with full stack traces - Policy mode: blocks capabilities for specific packages via SecurityException - Uses capability mappings from core module (java-interesting.cm) Also: - Add dependency-reduced-pom.xml to .gitignore - Disable AssignmentToForLoopParameter inspection (false positive on i++)
Dependency management: - Add protobuf.version (4.33.2) and mockito.version properties - Add asm-commons to parent dependencyManagement - Remove duplicate maven.plugin.version from maven-plugin module - Remove unused jetbrains:annotations dependency Agent fixes: - Fix classloader null check in CapabilityMapper resource loading - Remove unused import in CapabilityTransformer - Add extraArtifacts config to maven-invoker for jcapslock-agent Policy enforcement: - Add policy.yaml for quick-test example - Add BlockedExec test class and PolicyEnforcementTest - Add test-policy.sh E2E test script
Module restructuring: - Split core into core/ (lightweight) and core/analysis/ (SootUp) - Agent depends only on jcapslock-core (5.4MB vs ~20MB) - Maven plugin depends on jcapslock-core-analysis Runtime call graph capture: - Add RuntimeCallGraph for capturing capabilities during test execution - Add JUnit 5 extension (CapslockCallGraphExtension) for test integration - Add CallGraphAssertions for fluent graph assertions in tests - Add GraphMerger utility for combining Graph protos Refactoring: - Extract SootUp-specific methods from GraphProtoBuilder to SootGraphBuilder - Move CallGraphBuilder, ImplicitCapabilityDetector, UnifiedAnalyzer to analysis module - Use --release 17 instead of source/target for cleaner compilation - Fix shade plugin manifest handling
- Rename package from com.test to com.github.serj.jcapslock.examples.quicktest - Switch from exec-maven-plugin to maven-failsafe-plugin for integration tests - Add -Djdk.attach.allowAttachSelf=true to surefire argLine - Update policy.yaml and snapshot.json for new package structure
