Java CC review: Address findings #3
Description
At the time this issue was created, we have:
- around 122 issues detected by Sonar - need to be reduced constantly
- Unit test coverage is about 35%, need to be increased
- fake properties in gradle.properties file, that will influence all local repos, need to remove them and use -P, --project-props instead
- check the usage of catching Throwables, and keep only where it is a must (catch only exceptions we handle, and exceptions those are necessary to catch)
- remove checkstyle supression on method names (that allows underscores)
