I used OpenLiberty version 19.0.0.4 with JavaEE 8 on JRE runtume version 11 .
when i running application server , receive this warnings :
[WARNING ] CWWKS3103W: There are no users defined for the BasicRegistry configuration of ID com.ibm.ws.security.registry.basic.config[basic].
WARNING: An illegal reflective access operation has occurred

WARNING: Please consider reporting this to the maintainers of com.ibm.ws.util.ThreadContextAccessor

How can fix this ?
This is a known bug in OpenLiberty, see open-liberty#7180
