The error issue happened because the cursor failure is already the cause of the commit or rollback failure. This generates a circular reference when both of the exceptions are combined.

This situation can create stack overflow when the exception is logged in some logging libraries.

The solution don't add the cursor exception as the cause of the exception, this way it will not be wrongly combined creating a circular reference.
