All these started after I upgraded to 7.2

my java version is  
java -version  
java version "11.0.3" 2019-04-16 LTS  
Java(TM) SE Runtime Environment 18.9 (build 11.0.3+12-LTS)  
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.3+12-LTS, mixed mode)

And I don't find luck fixing or finding what these error means

They are warnings which you can ignore. The elastic folks will remediate the issues in future releases.
