Logger initialized with foreign class

Reports Logger instances that are initialized with a class literal from a different class than the Logger is contained in. This can easily happen when copy-pasting some code from another class and may result in logging events under an unexpected category and cause filters to be applied incorrectly.

A quick-fix is provided to replace the foreign class literal with one from the surrounding class.

Example:

public class Paramount { protected static final Logger LOG = Logger.getLogger(Critical.class); // ... other fields and methods }

After the quick-fix is applied:

public class Paramount { protected static final Logger LOG = Logger.getLogger(Paramount.class); // ... other fields and methods }

Configure the inspection:

  • Use the table to specify the logger factory classes and logger factory methods recognized by this inspection.

  • Use the Ignore loggers initialized with a superclass option to ignore loggers that are initialized with a superclass of the class containing the logger.

  • Use the Ignore loggers in non-public classes to only warn on loggers in public classes.
