Run PskTlsTest.java as a JUnit 5 test. It runs a client/server echo test, 10 times using Plaintext, and 10 times using TLS PSK.
- 100%: Plaintext tests #1 through #10 always pass.
- ~10%: TLS PSK test #1 intermittently passes (10%), or fails (90%) with exception
TlsFatalAlertReceived: bad_record_mac(20). - 100%: TLS PSK tests #2 through #10 always pass.
As a quick estimate, I seem to have to re-run the JUnit test about 10 times before I get all tests to pass. The rest of the runs, the first TLS PSK test fails.
Below are screenshots showing all tests passed (1 run of 10), versus all tests passed except the first TLS PSK test (9 runs out of 10).
If TLS PSK test #1 fails, the stack trace is:
