(My test vehicle is DBVisualizer.)\n\nTo fix this issue, I propose to implement setCatalog() in the same way as already implemented during connection setup. I would set up a PR for this that demonstrates the issue using a failing test case in the first commit and a fix in the second commit. \n","author":{"url":"https://github.com/eickler","@type":"Person","name":"eickler"},"datePublished":"2026-01-04T10:06:28.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/942/arrow-java/issues/942"}
