v1.2.0 - Refactor & Test Coverage

Changelog

Refactor

• Replace CopyOnWriteArrayList with ConcurrentHashMap in RedisManager for client storage
• registerClient now returns @NotNull and uses case-insensitive key matching to prevent duplicate IDs
• Remove CompletableFuture usage in RedisClient and simplify topic handling
• Move TimedRequestSerializer from net.bitbylogic.rps.gson to net.bitbylogic.rps
• Reduce TimedRequestSerializer access level to package-private
• Change null channel fallback to empty string in TimedRequestSerializer
• Introduce static shared GSON instance in ListenerComponent with enableComplexMapKeySerialization()
• Remove pretty printing from RedisManager GSON instance
• Change ListenerComponent(targetServerId, channel) constructor from private to public
• Change setAllowSelfActivation() from private to protected in RedisMessageListener
• Add @Contract annotations to fluent methods in ListenerComponent
• Add @CheckReturnValue to getData, getDataOrElse, and getRequestByID in ListenerComponent
• Add @CheckReturnValue to RedisManager#registerClient

Style

• Fix Javadoc paragraph formatting in RedisClient

Tests

• Add RedisManagerTest using JUnit 5 and TestContainers
• Add test coverage for duplicate client registration, message send/receive, self-activation, multiple listeners, server ID filtering, timed request timeout/success, and malformed JSON handling
• Add maven-surefire-plugin, junit-jupiter, and testcontainers-redis dependencies

Refactor/Cleanup!

Breaking Changes

• RedisManager.getSourceID() renamed to getServerId()
• RedisClient field ID renamed to clientId; getter updated accordingly
• ListenerComponent field target renamed to targetServerId
• RedisManager constructor signature changed, the Config-based overload now takes (Config, String) instead of (String, int, String, String, Config)

New Features

• Added a second RedisManager constructor accepting a pre-built Config object for more flexible Redis configuration
• Javadoc auto-build and publish to GitHub Pages via new .github/workflows/javadocs.yml workflow
• maven-javadoc-plugin added to pom.xml with Java 21 and lenient doclint settings

Improvements

• RedisClient internal collections migrated to thread-safe types: CopyOnWriteArrayList for listeners and timedRequests, ConcurrentHashMap for requestTimers
• Channel registration logic extracted into dedicated registerChannel() and registerRequestTopic() private methods in RedisClient, reducing constructor complexity
• Duplicate listener registration now logs a warning and returns early instead of silently adding a second instance
• JsonSyntaxException on the request topic is now caught and logged at WARNING level rather than crashing
• RedisManager connection errors now use Logger.log(Level.SEVERE, ..., exception) instead of printStackTrace()
• Gson instance in RedisManager made static final (shared across all instances)
• Debug format strings extracted to static final constants in RedisClient
• @NotNull / @Nullable annotations added throughout for improved null-safety documentation
• Comprehensive Javadoc added to all public methods and constructors across RedisClient, RedisManager, ListenerComponent, RedisMessageListener, RedisTimedRequest, and RedisTimedResponse
