  "message": "GH-1239: Fix memory leak when C Data import hits allocator limit mid-array (#1240)\n\n`ReferenceCountedArrowArray.unsafeAssociateAllocation` calls `retain()`\nbefore `wrapForeignAllocation`. If `wrapForeignAllocation` throws\n(allocator over its limit), the retain is never balanced, the reference\ncount stays elevated, and the C Data release callback never fires —\nleaking the producer\u0027s native memory.\n\n**Fix:** call `retain()` after `wrapForeignAllocation` returns. Same\nbehavior on the success path; on failure the existing `finally` in\n`ArrayImporter.importArray` drives the count to zero and fires the\nrelease callback.\n\n**Test:** `ImportOutOfMemoryTest` — exports a batch from a \"producer\"\nallocator, tries to import it into a too-small consumer, and asserts the\nproducer drains to zero after the OOM. Fails on the original code,\npasses with the fix.\n\nFixes: https://github.com/apache/arrow-java/issues/1239\n\n---------\n\nSigned-off-by: Sandesh Kumar \u003ckusandes@amazon.com\u003e\nCo-authored-by: Sandesh Kumar \u003ckusandes@amazon.com\u003e",
