[java] SpotBugs exclude NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE from the firefox.AddHasExtensions$1

[mk868]

User description

Description

As described in this comment, SpotBugs found some additional bugs in the code.
In this PR I fix part of the found problems.

SpotBugs error:

Executing tests from //java/src/org/openqa/selenium/firefox:firefox-lib-spotbugs
-----------------------------------------------------------------------------
M D NP: Possible null pointer dereference in org.openqa.selenium.firefox.AddHasExtensions$1.zipDirectory(Path) due to return value of called method  Dereferenced at AddHasExtensions.java:[line 104]

documentation

Solution:
Exclude this anonymous class from SpotBugs checks. A similar exclusion already exists for org.openqa.selenium.grid.config.Configs.

Motivation and Context

Fixing the actual problems is necessary before enabling full SpotBugs analysis, in order to not break the build.

Description

• Added a SpotBugs exclusion for the NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE bug pattern in the org.openqa.selenium.firefox.AddHasExtensions.* class.
• This change prevents SpotBugs from reporting possible null pointer dereference issues in this class, aligning with existing exclusions for similar cases.
• The update is part of efforts to fix issues before enabling full SpotBugs analysis to avoid build failures.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Best practice	Use precise class pattern matching to avoid over-exclusion of SpotBugs checks Consider using a more specific class pattern instead of wildcard (*) to avoid accidentally excluding unintended classes. Target only the specific inner class that needs the exclusion. java/spotbugs-excludes.xml [57-60] <Match> - <Class name="~org.openqa.selenium.firefox.AddHasExtensions.*"/> + <Class name="org.openqa.selenium.firefox.AddHasExtensions$1"/> <Bug pattern="NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE"/> </Match> Apply this suggestion Suggestion importance[1-10]: 6 Why: The suggestion to use a more specific class pattern instead of wildcard is a good practice to prevent unintended exclusions of SpotBugs checks. However, without context about the specific inner classes involved, we can't be certain this won't exclude necessary cases.	6
