JLeaks is a resource leaks repository collected from real-world projects which facilitates in-depth researches and evaluation of defect-related algorithms. Each defect in Leaks includes four aspects key information: project information, defect information, code characteristics, and file information. We will continuously update the repository as much as possible.
├─ JLeaksDataset // full data
│ ├─ bug_methods.zip // faulty methods
│ └─ fix_methods.zip // fixed methods
│ └─ bug_files.zip // faulty files
│ └─ files.zip // fixed files
│ └─ bug_bytecode_files.zip // faulty bytecode files
So far, JLeaks contains 1,094 real-world resource leaks from 321 open-source Java projects. Detailed information about these defects can be found in the JLeaks.xlsx.
