• http://techno-terminal.blogspot.com/2017/03/wildfly-82-heap-issue.html
• http://www.mastertheboss.com/jboss-server/wildfly-8/running-wildfly-with-jdk-8

It is recommended that standalone.conf and standalone.conf.bat should be updated along with the change in Java 8.

The current options:
JAVA_OPTS="-Xms1024m -Xmx1536m -Djava.net.preferIPv4Stack=true"

The suggested options for Java 8:
JAVA_OPTS="-Xms1024m -Xmx1536m -XX:MaxMetaspaceSize=256M -Djava.net.preferIPv4Stack=true"
