Some code smell reduction

[matteobaccan]

Hi

I have analyzed the source code with a static analyzer and I have removed some code smell

• Missing override
• Removed unused parameters
• Unused assignment
• Boolean literals redundant
• Unused import
• Catches combined
• Return redundant

All the best

Thanks!
You just need to digitally sign the Eclipse Contributor Agreement, which is a one-time thing for all of Eclipse.
I recently heard git "-S" is no longer a requirement at ECA. I will remove that step from CONTRIBUTING.md
