/**
* Static logger instances to be shared by implementation code in the main {@code com.launchdarkly.sdk.server}
* package.
*
* The goal here is 1. to centralize logger references rather than having many calls to
* {@code LoggerFactory.getLogger()} all over the code, and 2. to encourage usage of a basic set of
* logger names that are not tied to class names besides the main LDClient class. Most class names in
* the SDK are package-private implementation details that are not meaningful to users, so in terms of
* both being able to see the relevant area of functionality at a glance when reading a log and also
* convenience in defining SLF4J logger name filters, it is preferable to use these stable names.
*
* Code in other packages such as {@code com.launchdarkly.sdk.server.integrations} cannot use these
* package-private fields, but should still use equivalent logger names as appropriate.
