[CNAChino]

@klvnnsrikanth I just tried the example and works fine. Can you share files? I'll try to replicate on my end

[klvnnsrikanth]

@CNAChino Do you have any plans to migrate to JAVA 11 or JAVA 17?

[klvnnsrikanth]

I just now tried with maven and that seems to work. If I use gradle it doesn't work.

[CNAChino]

@klvnnsrikanth yes, we shall start working on Java 11 this upcoming quarter.

[klvnnsrikanth]

@CNAChino Java 11 is also EOL by Sep 2023, better to move to Java 17 directly or have two releases one supporting JAVA 11 and another for JAVA 17.
