   A sub-task of the autorest cleanup epic (#11068), requesting that stream-style serialization becomes the sole serialization method in the Java client emitter, removing the legacy Jackson-based code path.

   Category: Feature Request
   Area: emitter:client:java

   🔍 Analysis

   • This is a child task under the autorest generator code cleanup effort ([http-client-java] autorest generator code cleanup #11068), which aims to deprecate the autorest toolchain
   • The Java client emitter currently supports multiple serialization methods; the goal is to consolidate on stream-style serialization (azure-json based) and drop the older Jackson-based approach
   • This is an internal refactoring/cleanup that reduces maintenance surface and aligns with the migration away from autorest/Jackson
   • No duplicate issues found covering the same specific serialization cleanup task
   • No reproduction code needed — this is a planned engineering task, not a bug report

   📝 Suggested next steps

   • Identify all code paths in http-client-java that use the non-stream-style serialization
   • Remove or replace Jackson-dependent serialization logic with stream-style equivalents
   • Update/add tests to verify serialization behavior is preserved under stream-style only
   • Ensure the change is captured in a changelog entry
