Re: [External] : Re: JDK 18 Early-Access builds 23 are available
Hi David and Deepak,
I have finished my testing of build 18-ea+23-1525. I did not discover
any further problems beyond the security regression I mentioned before.
My results are described by
https://issues.apache.org/jira/browse/DERBY-7126.
Regards,
-Rick
