RepoBench v1.1 (Java)
Introduction
This dataset presents the Java portion of RepoBench v1.1 (ICLR 2024). The data encompasses a collection from GitHub, spanning the period from October 6th to December 31st, 2023. With a commitment to data integrity, we've implemented a deduplication process based on file content against the Stack v2 dataset (coming soon), aiming to mitigate data leakage and memorization concerns.

Coding agent session traces for LarsEckart/approvaltests-java-sessions
This dataset contains redacted coding agent session traces collected while working on git@github.com:approvals/ApprovalTests.Java.git. The traces were exported with pi-share-hf from a local pi workspace and filtered to keep only sessions that passed deterministic redaction and LLM review.
Data description
Each *.jsonl file is a redacted pi session. Sessions are stored as JSON Lines files where… See the full description on the dataset page: https://huggingface.co/datasets/LarsEckart/approvaltests-java-sessions.CWE-Bench-Java
CWE-Bench-Java
This repository contains the dataset CWE-Bench-Java presented in the paper LLM-Assisted Static Analysis for Detecting Security Vulnerabilities. At a high level, this dataset contains 120 CVEs spanning 4 CWEs, namely path-traversal, OS-command injection, cross-site scripting, and code-injection. Each CVE includes the buggy and fixed source code of the project, along with the information of the fixed files and functions. We provide the seed information for each CVE in… See the full description on the dataset page: https://huggingface.co/datasets/iris-sast/CWE-Bench-Java.java-trace-datasetstack_edu_javaarc-stack-javascriptkoch_test_2025_2This dataset was created using LeRobot.

Javanese Honorifics Dataset (Unggah-Ungguh - Released Version)
The Javanese language, spoken by over 98 million people, features a distinctive honorific system known as Unggah-Ungguh Basa. In this dataset we present UNGGAH-UNGGUH, a carefully curated dataset designed to encapsulate the nuances of Unggah-Ungguh Basa, the Javanese speech etiquette framework that dictates the choice of words and phrases based on social hierarchy and context.
