[keycloak-dev] Maven Surefire plugin - memory settings for JDK 8

Hello, Looking at global settings for Surefire plugin in keycloak/pom.xml: <artifactId>maven-surefire-plugin</artifactId> <configuration> <forkMode>once</forkMode> <argLine>-Xms512m -Xmx2048m -XX:MaxMetaspaceSize=512m</argLine> </configuration> 1) The heap space settings seems quite high. Is there some reason for 2g heap? If not, can we lower it say to 1g? 2) In JDK 8 permspace was replaced by metaspace which we might want to limit instead. Tomas
