I didn’t find that issue, but I didn’t try so many queries. I took a look directly into the github repo of jamdb, and found the issue was reported and supposedly fixed before:
https://github.com/erlangbureau/jamdb_oracle/issues/16
But since you’re finding the issue with the current version, the fix might not apply to all scenarios. There are three changesets mentioned there. I took a quick look but it’s Erlang code. Perhaps they’ll be more useful to you.
