🔧 Implementation Notes

This pull request introduces updates to several exception classes across the Selenium codebase to improve null-safety and enhance clarity. The changes primarily involve adding @NullMarked annotations to the classes and @Nullable annotations to method parameters where applicable.

Null-safety improvements:

• java/src/org/openqa/selenium/devtools/RequestFailedException.java: Added @NullMarked annotation to the class to enforce null-safety.

• java/src/org/openqa/selenium/grid/sessionmap/jdbc/JdbcException.java: Added @NullMarked annotation to the class and @Nullable annotations to method parameters (message and cause) to handle potential null values.

• java/src/org/openqa/selenium/remote/NoSuchDriverException.java: Added @NullMarked annotation to the class and updated constructors to include @Nullable annotations for reason and cause parameters.

• java/src/org/openqa/selenium/remote/UnreachableBrowserException.java: Added @NullMarked annotation to the class and updated constructors with @Nullable annotations for message and cause parameters.

• java/src/org/openqa/selenium/support/ui/UnexpectedTagNameException.java: Added @NullMarked annotation to the class and updated the constructor to include @Nullable annotations for expectedTagName and actualTagName parameters.

Thank you, @iampopovich for this code suggestion.

The support packages contain example code that many users find helpful, but they do not necessarily represent
the best practices for using Selenium, and the Selenium team is not currently merging changes to them.

We actively encourage people to add the wrapper and helper code that makes sense for them to their own frameworks.
If you have any questions, please contact us
