commit 3cfebe3672c03b29c9e486d363d6c61b00e7aa0a
Author: Jiri Ondrusek <on...@gmail.com>
AuthorDate: Fri Jul 10 10:02:15 2026 +0200

    Fixes #8860. Add GraalVM substitution for optional zstd-jni in httpclient5
    
    Substitute ZstdRuntime.available() to return false when zstd-jni is
    absent, preventing native image build failure on unresolved
    ZstdDecompressCtx. Follows existing Brotli and Xz substitution pattern.
