Hi all, ## Problem tobe fixed
The `empty` ssub-test of javax/net/ssl/ciphersuites/DisabledAlgorithms.java could hang util the jtreg timeout expires when the TLS handshake stalled after an error (e.g. server reports "Unsupported or unrecognized SSL message" while the client blocks in the handshake/read path). The stack trace and the detial test log shows in the JBS issue. In addition, the `default` subtest (failure path) contains a flaky assertion which required the server to observe an SSL exception. In some runs the client fails early (as expected) before the server get far enough to throw an SSL handshake exception, cause intermittent failres like "Expected SSL exception not thrown on server side". ## Fix solution in this PR - Make the handshake bounded and deteministic: - Configure `SOCKET_TIMEOUT` on both client and server SSLSocket instances - Explicitly call `SSlSocket.startHandShake()` on both sides. - Avoid cross-connection interference: - Run each ciper suite against it's own server instance congifured with that single suite. - Remove the extra application-data exho exchange, this test only needs the handshake and negotiated cipher suite. - Fix the flaky expectations in the failure path: - Accept the expected handshake failure if it is observed by either the client or the server. ## Additonal testing: - [ ] Run the test 10k times on linux-x64 - [ ] Run the test 10k times on linux-aarch64 --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8383570: Test DisabledAlgorithms.java intermittently timed out Changes: https://git.openjdk.org/jdk/pull/30995/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30995&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8383570 Stats: 96 lines in 1 file changed: 13 ins; 33 del; 50 mod Patch: https://git.openjdk.org/jdk/pull/30995.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30995/head:pull/30995 PR: https://git.openjdk.org/jdk/pull/30995
