[jdk21u-dev] RFR: 8358496: Concurrent reading from Socket with timeout executes sequentially

Thu Nov 13 21:56:03 UTC 2025

Backporting JDK-8358496: Concurrent reading from Socket with timeout executes sequentially. Updated SocketImpl so that the timeout applies to the total time waiting to acquire and read. Adds a new test to the existing java/net/Socket/Timeouts test. The test was minimally modified from the original commit for JDK version compatibility.

Ran GHA Sanity Checks (passed) and related test (passed).
