Description

This pull request includes several refactorings to improve code readability and consistency across multiple files, primarily by replacing lambda expressions with method references and simplifying conditional checks.

Code readability improvements:

• java/src/org/openqa/selenium/chromium/ChromiumDriver.java: Replaced lambda expression with method reference in protected ChromiumDriver constructor.
• java/src/org/openqa/selenium/devtools/SeleniumCdpConnection.java: Replaced lambda expressions with method references in create method and simplified if condition to use isEmpty() instead of !isPresent(). [1] [2]
• java/src/org/openqa/selenium/firefox/FirefoxDriver.java: Replaced lambda expression with method reference in private FirefoxDriver constructor.
• java/src/org/openqa/selenium/remote/RemoteWebDriver.java: Replaced lambda expression with method reference in addCredential method.

Test code simplification:

• java/test/org/openqa/selenium/NoSuchShadowRootTest.java: Simplified exception assertion by replacing lambda expression with method reference in getNoSuchShadowRoot test method.
• java/test/org/openqa/selenium/grid/node/relay/RelayOptionsTest.java: Simplified exception assertion by replacing lambda expression with method reference in protocolVersionThrowsConfigException test method.
• java/test/org/openqa/selenium/grid/server/BaseServerOptionsTest.java: Simplified exception assertion by replacing lambda expression with method reference in externalUriFailsForNonUriStrings test method.

Motivation and Context

While often it could be a matter of taste, method references are more clear and readable compared to lambdas.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add null checks to prevent potential NullPointerException in stream operations The stream concatenation and collection could fail with null values from the credential map. Add null checks to prevent NullPointerException. java/src/org/openqa/selenium/remote/RemoteWebDriver.java [1247-1250] Stream.concat( - credential.toMap().entrySet().stream(), + Objects.requireNonNull(credential.toMap()).entrySet().stream(), Stream.of(Map.entry("authenticatorId", id))) + .filter(e -> e.getKey() != null && e.getValue() != null) .collect(Collectors.toUnmodifiableMap(Map.Entry::getKey, Map.Entry::getValue))); Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion addresses a potential runtime error by adding null checks for credential map values, which could prevent NullPointerException in production code.	8
General	Add logging for suppressed exceptions to improve error diagnostics and debugging Consider handling the suppressed exception by logging it rather than just adding it to the suppressed exceptions list, as it contains important connection cleanup error details. java/src/org/openqa/selenium/chromium/ChromiumDriver.java [152-154] try { client.ifPresent(HttpClient::close); } catch (Exception ex) { + LOG.log(Level.WARNING, "Failed to close HTTP client", ex); e.addSuppressed(ex); } Apply this suggestion Suggestion importance[1-10]: 6 Why: Adding logging for suppressed exceptions would improve debugging capabilities by making cleanup errors more visible, while still maintaining the original exception handling behavior.	6
