Worked on stabilizing the aarch64 native launcher for the elastic/elasticsearch repository, focusing on improving deployment reliability for ARMv8.0-A CPUs. Addressed startup crashes caused by LSE atomics by pinning the launcher to compatibility mode using the -march flag, mirroring a previous x86_64 stabilization approach. This targeted fix reduced the risk of architecture-specific failures and enhanced cross-architecture parity within the codebase. Leveraged GraalVM for native image compilation and backend development, implementing changes in Groovy to ensure minimal impact on the existing baseline. The work prioritized robust startup behavior and maintainability for ARM deployments without introducing unnecessary complexity.
