If no plugin is found with the given name, the version command will
search all loaded plugins to find a case insensitive partial match for
the specified name and print to the sender all matches.
Previously, the method could be called with a null MetadataStore and stored.
In later execution null pointer exceptions would be generated when checking
for the plugin that the set Metadata belongs to.
Additionally, places where a plugin is referenced will now throw an
IllegalArgumentException if specified plugin is null. Using null would be an
obvious logical flaw, and in some cases produce additional exceptions later
in execution.
This change lets JavaPluginLoader use a temporary HashSet to store
methods that could possibly have the EventHandler annotation. Duplicates
are prevented by the nature of a Set.
Registering parent listeners is a breaking change for any listener
extending another listener and expecting parent listeners to not be
called. Changing this is justified by the ease-of-use and proper object
inheritance design. If this is undesired behavior, the method may be
overridden without reapplying the method with the EventHandler notation.
PlayerChatEvent is now Deprecated. It should be fired asynchronously, but
has not been so traditionally. To do so would massively break plugins that
rely on it.
AsyncPlayerChatEvent now replaces PlayerChatEvent. It uses comparable
functionality, but can be fired without synchronizing to the event manager.
The event will sometimes fire synchronously if triggered by a plugin.
Because PlayerChatEvent is now deprecated, PlayerCommandPreprocessEvent will
no longer extend PlayerChatEvent. This is almost completely source and
binary compatible, bar plugins that downcast to PlayerChatEvent.
Additionally, some methods that are non-functional have been marked
deprecated and indicate such.
Additionally, new constructors are now provided to allow for lazier
initialization of the receiving player set. A note has been added stating
plugins should be prepared for UnsupportedOperationExceptions if the caller
provides an unmodifiable collection.
