Introduces new FDv2 file-data loading/watching paths and refactors the legacy
FileDataSourceImplonto them; correctness of update/persist semantics and file-watching behavior could affect SDK initialization and store writes.Overview
Adds FDv2 support for file-based flag data by introducing
FileData.initializer()(one-shot load) andFileData.synchronizer()(optional auto-update watcher), built on a new sharedFileDataSourceBasethat produces FDv2ChangeSet/status results and supports configurable duplicate-key handling.Refactors the legacy
FileDataSourceImplto delegate to the newFileSynchronizerand adapt FDv2 results back intoDataSourceUpdateSink.initcalls, while adding a newshouldPersistconfiguration (legacydataSource()defaults to persisting for backwards compatibility; FDv2 initializer/synchronizer default to not persisting). Also removes the SDK-localIterableAsyncQueuein favor ofcom.launchdarkly.sdk.collections.IterableAsyncQueue, updates imports/tests accordingly, and bumpslaunchdarkly-java-sdk-commonto2.2.1.Written by Cursor Bugbot for commit c3f79d5.
