Objective: 10 open Dependabot alerts (3 high, 4 medium, 2 low) and 1 open code scanning alert (information exposure through exception) accumulate security risk and block compliance checks. Approach: Update all packages across Node, Python, and Java to their latest stable versions. Fix the code scanning alert by replacing raw exception messages with a generic error string in the HTTP response — stack traces are still logged server-side for debugging. Evidence: Full build and test suites pass across all three ecosystems. Node: pnpm build + vitest — 18/18 tests pass with TypeScript 6.0.2. tsconfig.json updated with "types": ["node"] and "ignoreDeprecations": "6.0" for TS6 compatibility. Python: pytest — 40/40 tests pass. uv.lock updated for both packages. hybrid tests skip as expected (optional deps not installed locally). Java: mvn clean verify — 502/502 tests pass (448 core + 54 cli). maven-compiler-plugin 3.14.1→3.15.0, spotbugs 4.9.8.2→4.9.8.3. Security alerts addressed: - Code scanning #30: hybrid_server.py no longer leaks str(e) to client - Dependabot #25-27 (vite): updated to ^8.0.8 - Dependabot #30 (pillow), #31 (pytest), #29 (cryptography), #28 (transformers), #24/#23 (Pygments): lock files pull patched versions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Batch Processing Example
Demonstrates processing multiple PDFs in a single invocation to avoid repeated Java JVM startup overhead.
Prerequisites
- Python 3.10+
- Java 11+ (on PATH)
Example
batch_processing.py shows two methods for batch conversion:
- File list — Pass multiple PDF paths as a list
- Directory — Pass a directory path (recursively finds all PDFs)
Both methods use a single JVM invocation, which is significantly faster than calling the CLI once per file.
Run:
pip install -r requirements.txt
python batch_processing.py
Sample Output
Found 4 PDFs in pdf/
