[OSS ONLY] Fix to throw error instead of warning in JDBC test logfile

[pranavJ23]

Description

[Describe what this change achieves - Guidelines below (please delete the guidelines after writing the PR description)]

1. What is the change? This is best described in terms of “Currently, Babelfish does X. With this change it now does Y.” Think of “What did it used to do?” and “What does it do now?”

2. Why was the change made? What drove our desire to put effort into the change?
3. How was the code changed should only appear for large commits. This can serve as a rough roadmap to what’s contained in the commit. It should be very high level; if it’s directly referencing code it’s probably too detailed. It’s also critical that this section of a commit message does not try to replace proper code documentation (ie, block comments or README files). Generally, this section should only appear if the commit itself is large enough that it’s helpful to provide a roadmap to someone looking at the commit.
4. The last descriptive piece is the “title” for the commit: the very first line of the commit message, which should typically be less than 80 characters. A good title is critical, because it’s the only thing that shows up in places like the Github commit listing. No one’s got time to read through full commit messages when trying to find a single commit out of dozens.
