This pull request includes several changes to improve code readability and consistency in the Selenium project. The most important changes involve replacing deprecated string methods and updating header content type handling.

Improvements to code readability and consistency:

• java/src/dev/selenium/tools/modules/ModuleGenerator.java: Simplified the error message concatenation by removing unnecessary new String conversion.
• java/src/org/openqa/selenium/Cookie.java: Replaced ("".equals(path)) with path.isEmpty() for better readability.
• java/src/org/openqa/selenium/Platform.java: Replaced ("".equals(matcher)) with matcher.isEmpty() for better readability.
• java/src/org/openqa/selenium/remote/codec/AbstractHttpCommandCodec.java: Removed unnecessary toString() call on JSON_UTF_8 when setting the content type header.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	✅ Fix error message content display Suggestion Impact: The commit implemented the suggestion by converting the ByteArrayOutputStream (bos) to a string using toString() method, but with additional improvements: using StandardCharsets.UTF_8 for proper encoding and reformatting the error message with String.format for better readability. code diff: throw new RuntimeException( - "Unable to process module:\n" + "jdeps " + String.join(" ", jdepsArgs) + "\n" + bos); + String.format( + "Unable to process module:%njdeps %s%n%s", + String.join(" ", jdepsArgs), bos.toString(StandardCharsets.UTF_8))); The error message construction should include the actual error output from the process execution, which is currently missing. Access the error content from bos using bos.toString() or new String(bos.toByteArray()). java/src/dev/selenium/tools/modules/ModuleGenerator.java [214-215] throw new RuntimeException( - "Unable to process module:\n" + "jdeps " + String.join(" ", jdepsArgs) + "\n" + bos); + "Unable to process module:\n" + "jdeps " + String.join(" ", jdepsArgs) + "\n" + bos.toString()); [Suggestion has been applied] Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies that the error message might not properly display the process output since 'bos' needs to be converted to a string. This could significantly impact error debugging and troubleshooting.	Medium
	Fix cookie format syntax The semicolon after 'secure' creates invalid cookie syntax. Remove the trailing semicolon to conform to cookie format standards. java/src/org/openqa/selenium/Cookie.java [280] -+ (isSecure ? ";secure;" : "") ++ (isSecure ? ";secure" : "") Apply this suggestion Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies a syntax issue in cookie formatting where an extra semicolon after 'secure' could cause compatibility issues with some browsers or systems parsing the cookie string.	Medium

Can we use bos.toString(StandardCharsets.UTF_8) with String.format() for correctness, readability, and maintainability.
