… omitted port Tighten the port validation to 1–65535 (port 0 is reserved and invalid for client connections). Four builder-based tests were not calling withPort() at all, so the port field defaulted to 0 and slipped through unnoticed before the validation was added. Each test now passes the actual test-server port via FLIGHT_SERVER_TEST_EXTENSION.getPort(). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Converts testUnencryptedConnectionProvidingInvalidPort to a @ParameterizedTest covering 0, -1, 65536, and 65537, explicitly exercising the port-0 rejection added to NettyClientBuilder.build(). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

What's changed
Port validation in
NettyClientBuilder.build()is tightened to explicitly disallow port 0, as it is not a valid destination port number for a client.Tests that made use of port 0 were updated to use a valid port under the new validation.
Are these changes tested?
Yes.
ConnectionTest.testUnencryptedConnectionProvidingInvalidPortwas expanded to cover more invalid ports, including port 0.This change was created with AI assistance (Claude Code). All lines were manually reviewed by a human. The output is not copyrightable subject matter.
Closes #1271.
