> The {{getServices()}} method of {{Tracker}} instances returned by the {{OsgiWhiteboard}} is synchronized, which leads to lock contention and the related performance hit for example when lots of queries are executed in parallel, as each query execution looks up the available index provider services. We should refactor the {{Tracker}} implementation to avoid synchronization of the {{getServices()}} method.
