Description

This pull request includes several changes to improve the code by replacing the Files.write method with the more concise Files.writeString method. Additionally, there is a minor refactor to simplify a loop structure.

Codebase simplification:

• java/src/org/openqa/selenium/grid/jmx/MBean.java: Refactored a for loop to use enhanced for-loop syntax for better readability.

Method replacement:

• java/src/org/openqa/selenium/grid/node/docker/DockerSessionFactory.java: Replaced Files.write with Files.writeString to simplify writing string content to files.
• java/test/org/openqa/selenium/UploadTest.java: Updated method to use Files.writeString for writing string content to temporary files.
• java/test/org/openqa/selenium/edge/EdgeOptionsTest.java: Changed file writing method to Files.writeString for better readability and simplicity.
• java/test/org/openqa/selenium/environment/webserver/AppServerTestBase.java: Simplified file writing by using Files.writeString instead of Files.write.

Motivation and Context

I changed the method calls for writing strings to standard ones from Java 11 to include more standard solutions from the language library. I also replaced looping through the collection with an iterator for better code readability.

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 PR contains tests

🔒 Security concerns File Permission: The code creates temporary files with default permissions which could potentially be accessed by other users on the system. Consider setting appropriate file permissions when creating temporary files containing potentially sensitive data like session capabilities.

⚡ Recommended focus areas for review Bug The createFile method writes content to the directory path instead of the newly created file path, which will cause file corruption or errors Error Handling The method should close file resources properly in case of exceptions during file writing operations

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Fix critical bug where content is written to wrong file path Fix incorrect file path usage - currently writing to directory path instead of the newly created file path. java/test/org/openqa/selenium/grid/node/NodeTest.java [919] -Files.writeString(directory.toPath(), content); +Files.writeString(f.toPath(), content); Apply this suggestion Suggestion importance[1-10]: 10 Why: This is a critical bug fix where content is being written to the directory path instead of the newly created file path, which would cause file operation failures and potential data corruption.	10
General	Use explicit character encoding instead of platform-dependent default charset to ensure consistent file writing Specify a charset explicitly instead of using the default charset to ensure consistent encoding across different platforms and environments. java/src/org/openqa/selenium/grid/node/docker/DockerSessionFactory.java [457-458] Files.writeString( - Paths.get(path, "sessionCapabilities.json"), capsToJson, Charset.defaultCharset()); + Paths.get(path, "sessionCapabilities.json"), capsToJson, StandardCharsets.UTF_8); Apply this suggestion Suggestion importance[1-10]: 6 Why: Using explicit UTF-8 encoding instead of platform-dependent default charset is a good practice to ensure consistent behavior across different environments. While not critical, it prevents potential encoding issues.	6
