Whenever using a log level, one should check if it is actually enabled, or otherwise skip the associate String creation and manipulation, as well as any method calls. An alternative to checking the log level are substituting parameters, formatters or lazy logging with lambdas. The available alternatives depend on the actual logging framework.

This version of the CodeQL Action was deprecated on January 18th, 2023, and is no longer updated or supported. For better performance, improved security, and new features, upgrade to v2. For more information, see https://github.blog/changelog/2023-01-18-code-scanning-codeql-action-v1-is-now-deprecated/

ubuntu-latest pipelines will use ubuntu-24.04 soon. For more details, see https://github.com/actions/runner-images/issues/10636

A logger should normally be defined private static final and be associated with the correct class. `private final Log log;` is also allowed for rare cases where loggers need to be passed around, with the restriction that the logger needs to be passed into the constructor.

This rule detects when a constructor is not necessary; i.e., when there is only one constructor and the constructor is identical to the default constructor. The default constructor should has same access modifier as the declaring class. In an enum type, the default constructor is implicitly private. UnnecessaryConstructor (Priority: 3, Ruleset: Code Style) https://docs.pmd-code.org/pmd-doc-7.8.0/pmd_rules_java_codestyle.html#unnecessaryconstructor

Uncommented Empty Constructor finds instances where a constructor does not contain statements, but there is no comment. By explicitly commenting empty constructors it is easier to distinguish between intentional (commented) and unintentional empty constructors.

Enforce a policy for braces on control statements. It is recommended to use braces on 'if ... else' statements and loop statements, even if they are optional. This usually makes the code clearer, and helps prepare the future when you need to add another statement. That said, this rule lets you control which statements are required to have braces via properties. From 6.2.0 on, this rule supersedes WhileLoopMustUseBraces, ForLoopMustUseBraces, IfStmtMustUseBraces, and IfElseStmtMustUseBraces.

Reports exceptions that are thrown from within a catch block, yet don't refer to the exception parameter declared by that catch block. The stack trace of the original exception could be lost, which makes the thrown exception less informative. To preserve the stack trace, the original exception may be used as the cause of the new exception, using `Throwable#initCause`, or passed as a constructor argument to the new exception. It may also be preserved using `Throwable#addSuppressed`. The rule actually assumes that any method or constructor that takes the original exception as argument preserves the original stack trace. The rule allows `InvocationTargetException` and `PrivilegedActionException` to be replaced by their cause exception. The discarded part of the stack trace is in those cases only JDK-internal code, which is not very useful. The rule also ignores exceptions whose name starts with `ignored`.
