Oracle logs filled with “java.lang.Throwable: No Error”?

I have enabled JDBC logging for my Oracle connection. I would like the log to only contain the text of executed queries, but it is filled with the below error.

Any suggestions for what may be causing this trace, how I can fix it, and/or how I can limit my logging to the text of executed queries?
