Adjust the THRESHOLD constant to use _adjustTimeout_() so it scales appropriately with the test environment's timeout factor, consistent with other tests such as TcpTimeout.java. Reduced the default value from 3000 ms to 2000 ms.
The value is additionally capped at 9 seconds to ensure it stays well below the full exponential backoff retry cycle (1 + 2 + 4 + 8 = 15 s), preserving the test's intent of verifying that an ICMP Port Unreachable response causes a quick failure rather than waiting through all retries. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - Fix comment - Use timeout factor for threshold and reduce default to 2 secs Changes: https://git.openjdk.org/jdk/pull/33000/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=33000&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8392827 Stats: 8 lines in 1 file changed: 4 ins; 0 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/33000.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/33000/head:pull/33000 PR: https://git.openjdk.org/jdk/pull/33000
