Re: What is this issue with java.util.zip.CRC32C?

Yes, thank you, but I know that. My project is still on 8.x path until I 
migrate to Jakarta EE.

But for the sake of a reproducible test case, it doesn't matter if TomEE 
9.x or 10.x, it just have to be at least 9.x so that the source level is 
greater than 8.
The web application doesn't have to do anything. Just create the 
project, open it in Netbeans and wait... the lines with "Even though the 
source level of ....." will start coming into the messages.log file of 
Netbeans.
