Upgrading Java from 7u161 to 7u171 prevents JBoss AS 7.1.1.Final from starting. I know JBoss AS 7.1.1 is EOL but for compatibility reasons, we still need to run this version.
Very early in the startup, a NullPointerException occurs in some JBoss method :
Calling "C:\PRODUCT\jboss-as-7.1.1\bin\standalone.conf.bat"
"JAVA_OPTS already set in environment; overriding default settings with values: -server -Xrs -Xms256m -Xmx512m -XX:MaxPermSize=128m -Dproduct.home=C:\PRODUCT -Djboss.server.base.dir=C:\PRODUCT\jboss-as-7.1.1\standalone -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true -Djboss.modules.system.pkgs=org.jboss.byteman -Djboss.server.default.config=standalone.xml "
