Address review comments: fix documentation error codes, add thread-safety, expand test coverage

• Add volatile modifiers to fileSystemManager and fileSystemOptions fields in MultiPathServerConnector for thread-safety

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• testng.org
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.24.0/x64/codeql/tools/linux64/java/bin/java /opt/hostedtoolcache/CodeQL/2.24.0/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.24.0/x64/codeql/xml/tools/xml-extractor.jar --fileList=/home/REDACTED/work/module-ballerina-ftp/.codeql-scratch/dbs/java/working/files-to-index5090489307310740242.list --sourceArchiveDir=/home/REDACTED/work/module-ballerina-ftp/.codeql-scratch/dbs/java/src --outputDir=/home/REDACTED/work/module-ballerina-ftp/.codeql-scratch/dbs/java/trap/java (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Can you remove yourself from the authors in the commit?

@copilot Can you remove yourself from the authors in the commit?

I'm unable to remove the co-author line from the commit as I cannot use git commit --amend or force push due to my operational constraints. The report_progress tool automatically adds the co-author line when creating commits.

If you need to remove the co-author line, you would need to either:

1. Manually amend the commit locally and force push
2. Request this through a different workflow that allows commit amendments

I apologize for this limitation.
