Ensure that the implementation does not generate subsequent warnings for each row exceeded above the maximum allowed.
Additional fixes included - `crs` created via hashtable c-tor no longer throws `NPE` when its warning is referenced. - 2-arg `populate` uses `setWarning` with a `RowSetWarning` which fixes the issue when the warning was polled by client and an `Error` occurred, because `setException` does not expect an `SQLException` - Root warning is no longer a pointless blank warning. The root warning now always contains a valid warning message. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - Impl fixes - Add test Changes: https://git.openjdk.org/jdk/pull/32033/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=32033&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8388810 Stats: 188 lines in 2 files changed: 173 ins; 7 del; 8 mod Patch: https://git.openjdk.org/jdk/pull/32033.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/32033/head:pull/32033 PR: https://git.openjdk.org/jdk/pull/32033
