Summary

  • Retain application-to-dependency-JAR Java call facts in the SootUp provider graph.
  • Preserve exact dependency owner, method, JVM descriptor, classpath entry, bytecode evidence, certainty, provenance, and dynamic abstention.
  • Keep JDK/runtime, phantom, unresolved, and dependency-origin callers out of provider facts.
  • Preserve application evidence shape and legacy application fact IDs.

Validation

  • make adapter-test — 52/52 passed
  • Focused dependency integration suite — 5/5 passed
  • git diff --check — passed
  • Final Engram-grounded CodeRabbit-style review — NO_ACTIONABLE_COMMENTS

Scope

  • No SootUp source changes.
  • No FLPATH-5013/5014 reporting changes.
  • Maven coordinate metadata remains scoped to follow-up FLPATH-5112.

Jira: FLPATH-5086

Summary by CodeRabbit

  • New Features

    • Java analysis now includes calls from application code to dependency libraries, with dependency ownership and available source or bytecode details.
    • Dependency calls are distinguished from application calls, even when they would otherwise share an identifier.
    • Dependency classpaths support trailing wildcards, and classes in WAR files are attributed to the containing archive.
  • Bug Fixes

    • Duplicate and invalid dependency classpath entries are handled, with an error reported when a nonempty classpath has no valid entries.
    • Calls to unavailable dependency methods are omitted; uncertain dispatch and dynamic dependency calls retain appropriate uncertainty status.

Walkthrough

The provider now resolves application calls to dependency targets and records target origin and location context. The normalizer assigns origin-aware fact IDs and adds dependency metadata to evidence. Tests cover dependency resolution, classpath handling, dispatch certainty, evidence, and ID stability.

Changes: Dependency Call Edges

Layer / File(s) Summary
Dependency inputs and target context
src/main/java/com/projectlightpath/analysis/java/CallEdge.java, src/main/java/com/projectlightpath/analysis/java/SootUpInputLocationFactory.java, src/main/java/com/projectlightpath/analysis/java/SootUpBaseGraphProvider.java
CallEdge carries application or dependency target context. The input factory creates a view from application and valid dependency locations. The provider passes dependency mappings to call extraction.
Call extraction and dependency resolution
src/main/java/com/projectlightpath/analysis/java/SootUpCallGraphExtractor.java, src/test/java/com/projectlightpath/analysis/java/SootUpDependencyBoundaryIntegrationTest.java
The extractor discovers application methods, classifies calls, and resolves dependency target context. Integration tests cover dependency facts and evidence, dispatch certainty, dependency classpath handling, and targets absent from the dependency artifact.
Origin-aware fact IDs and evidence
src/main/java/com/projectlightpath/analysis/java/ProviderFactNormalizer.java, src/test/java/com/projectlightpath/analysis/java/JavaAnalysisAdapterTest.java
The normalizer assigns IDs from edge origin and identity while retaining legacy application IDs when possible. Dependency evidence includes target and location attributes. Tests check deterministic IDs and dependency proxy_dispatch certainty.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: Minimal · up to 4ec46

This change keeps dependency-JAR call facts and their origin evidence in the Java analysis output. The earlier concern about calls to classes inside WAR files being dropped is now handled and covered by a test. No actionable merge-blocking risk remains.

Security architecture risk: Low · up to 4ec46

Dependency coverage expands the information carried by analysis results while preserving caller restrictions and dynamic-call abstention. No introduced security failure was established, but duplicate-class attribution and downstream handling of filesystem paths remain incompletely verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated security-relevant effect concerns result integrity and provenance within an analysis context: configured dependency contents can now contribute target facts and filesystem metadata. Broader tenant exposure or downstream authority cannot be determined from the inspected producer and adapter code.

Trust Boundaries and Controls

  • observed — Dependency attribution requires the resolved target class's input location to appear in the dependency map; missing classes or mappings drop the edge. Application attribution instead uses owner-name membership. The integration test asserts correct attribution between duplicate dependency classes, runtime-target exclusion, and application-only callers, but does not establish application/dependency same-name resolution precedence.

Explanation

The title names the main change: preserving dependency-boundary Java call facts in the SootUp provider graph. The changeset adds dependency target context to CallEdge, dependency-aware fact IDs in ProviderFactNormalizer, a SootUpCallGraphExtractor, input location handling for dependency classpath entries, and tests for dependency-boundary facts. The ticket prefix FLPATH-5086 matches the PR objectives. The title is short, specific, and free of noise.

`Builder.dependencyClasspath` into matching `.jar` and `.JAR` paths before the
`isValidInputLocation` check. Normalize and deduplicate each result through
`dependencyPaths`, then create an input location and record the path in
`dependencyEntries`; preserve validation for each expanded path.

- Around line 147-149: Update certainty assignment in SootUpCallGraphExtractor
so virtual dispatch candidates are classified before certainty is chosen; keep
dependency targets possible when dispatch may select among implementations, and
assign DEFINITE only when the target is established as exact.

- Line 58: Update SootUpInputLocationFactory’s dependencyEntries mapping so
SootUp class-source locations for classes under WEB-INF/classes and nested JARs
resolve to their owning WAR dependency entry. Preserve the outer WAR location as
the dependency target, and ensure SootUpCallGraphExtractor.dependencyTarget can
find the mapping for those contained classes.

- Line 173: Resolve the invoked method signature through the class hierarchy
before checking finality, so an inherited final method such as Base.value() is
recognized for Child.value() and the dependency edge remains DEFINITE. Update
the finality checks in the call-graph extraction flow, using the hierarchy
resolution behavior available in the existing SootUp APIs; add a non-final
subclass fixture that inherits a final method.
