• Metadata generated at Some plan to write additional unit tests for the class library need GraalVM Reachability Metadata linghengqian/graalvm-trace-metadata-smoketest#1 .

• I work on this issue.

• I've observed some very unreasonable Junit errors when executing jetcd-core's nativeTest, and I think I've recently had to identify some underlying issues on the Junit side. Refer to https://github.com/linghengqian/graalvm-trace-metadata-smoketest/tree/main/jetcd-core .

[linghengqian]

• After I performed a series of exciting processing, jetcd-core's nativeTest is completed.

[linghengqian]

• I completed the nativeTest verification of io.etcd:jetcd-core:0.7.6 at Add GraalVM Reachability Metadata and corresponding nativeTest for Etcd integration apache/shardingsphere#29755. Fixing nativeTest actually only requires the GraalVM Reachability Metadata of io.netty:netty-transport-classes-epoll:4.1.99.Final.
• I've opened Add support for io.netty:netty-transport-classes-epoll:4.1.99.Final #437. The current issue will be closed.
