Research direction
Investigate Dubbo's dependency on Guava, specifically the com.google.common.util.concurrent.AbstractFuture class that uses sun.misc.Unsafe. Check if upgrading Guava to a version that resolves the deprecation is feasible. If not, consider replacing the usage with Java's built in VarHandle or LockSupport. The maintainer should review the linked Guava issue (https://github.com/google/guava/issues/7811) for updates.
