summary

Systematic study of 333 real bug reports identifies that 40.2% have small repro tests, over 80% manifest as exceptions, syntactic, or semantic errors, and the hardest causes are sugaring, region restoration, type inference. The authors build JD-Tester differential framework using Java father and hyphest generators, run it on three decompilers (including CFR and Fernflower variants) and report 62 real-world bugs found, with many semantic errors hard to detect without source.
