February 2025 — DataDog/java-profiler: Focused feature work delivering enhanced code cache import patching across relocation sections with improved handling of imported functions and multi-entry imports. Refactored patching logic for scalability and added tests to verify imports from both .rela.plt and .rela.dyn. No discrete bug fixes recorded this month; improvements prioritized reliability and test coverage.

January 2025 monthly summary for corretto/corretto-17: Implemented AArch64 SVE runtime validation to prevent SIGILL when prctl is disallowed, enhancing VM stability and reliability.

December 2024 monthly summary for the corretto/corretto-21 repository. The primary deliverable was a hardening fix for AArch64 SVE vector length handling to prevent VM crashes when prctl is disallowed. Implemented pre-enable validation of SVE vector length (must be a power of two and a multiple of 16) and a safe fallback that disables SVE with a warning if the length cannot be determined or is invalid. This change enhances stability across ARM environments with restricted prctl usage and reduces risk of SIGILL crashes in production.
