There was a problem hiding this comment.
Looks good to me. Left one comment.
Utils.handleThrowable now returns RuntimeException so callers can write `throw Utils.handleThrowable(e)`, letting the compiler verify the catch block always completes abruptly. This removes the redundant `throw new AssertionError(...)` line flagged in review, while relying on existing assertThrows coverage to confirm exceptions are not swallowed.

The GPUKnnFloatVectorQuery change is unrelated to this PR's scope (propagating Error subclasses instead of wrapping them). It addresses a separate pre-existing bug on main where the multi-partition GPU rewrite path bypasses Lucene's exact-search fallback for highly selective filters, which surfaces as an intermittent TestCuVSGaps failure on certain randomized seeds. Reverting it here per review feedback; tracked separately in its own issue so it can be reviewed on its own merits. Signed-off-by: Shaunak Kapur <shaunakk@nvidia.com>

Summary
Replace the broad RuntimeException wrappers in fieldsWriter and fieldsReader across the plain, scalar quantized, and binary quantized accelerated vector formats with Utils.handleThrowable.
This preserves IOException, RuntimeException, and Error instances instead of discarding their type, cause, and stack information. It also documents and tests the shared Error propagation contract.
Add focused helper and vector format regression coverage. The call site tests verify that IOException and RuntimeException instances are propagated unchanged, while the helper test verifies exact Error identity.
Testing
The call site tests were also run against the previous wrappers and correctly failed for IOException and RuntimeException identity.
Closes #2474
