(In reply to Michael Joyner from comment #0) > ```Java > package my.package.jdbi; > > public interface Dao { > > String LABELS_BOOK_TITLES = "labels_book_titles"; > String LABELS_CHAPTERS = "labels_chapters"; > String TRAIN_ARTICLE_DATA = "training_article_data"; > String TRAIN_ARTICLE_DATA_CLEAN = "training_article_data_clean"; > String TRAIN_ARTICLE_LABELS = "training_article_labels"; > > @SqlUpdate("update "+TRAIN) //***** THIS IS WHERE THE ERROR HAPPENS, > WHEN TRYING TO AUTO COMPLETE THE PARTIAL WORD. > void resetBookTitleTrainingData(); > > } > > interface DaoExtended extends Dao { > // ... > } > ``` Thanks, I can reproduce after just adding: public @interface SqlUpdate { String value(); }

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
