duplicate keycloak_quarkus_java_opts (Xms Xmx) used

[roumano]

SUMMARY

We can change the variable keycloak_quarkus_java_opts for java memory (the default value is -Xms1024m -Xmx2048m )

It's used in the templates/keycloak-sysconfig.j2 so the service is start with this option.

Sadly, it's also existing a Xms & Xmx attribut harcoded in the kc.sh as your can see :

grep Xms /opt/keycloak/keycloak-24.0.1/bin/kc.sh 
         JAVA_OPTS_KC_HEAP="$JAVA_OPTS_KC_HEAP -Xms64m -Xmx512m"

So, when start the keycloak service, it's using both argument .

Please found the full command used to start the service :

EXPECTED RESULTS

a unique Xms & Xmx arguement on the started service

/etc/alternatives/jre_17/bin/java ... ... -Xms1024m -Xmx2048m ... ...

ACTUAL RESULTS

/etc/alternatives/jre_17/bin/java ... ... -Xms64m -Xmx512m  ... ... -Xms1024m -Xmx2048m ... ...
