I have tried to add --add-opens in JVM args as well but that dosn't work.

Any solution or anything i am doing wrong ?

The -add-opens should work given the message.

What was the add-open added?

i added in jvmArgs , is version 3.8.1 is compatible with JDK 17 ?? 

--add-opens java.base/java.lang=ALL-UNNAMED

[Henri Tremblay]

the error is about java.util. So you should put --add-opens java.base/java.util=ALL-UNNAMED

Hi Thanks henri,

Issues were resolved when I updated my Ehcache version to 3.9.x from 3.8.x, also warnings were from java.util and got resolved,

Thank you for your help cheers!
