Hi, You can add "java.lang" to WildFly property "jboss.modules.system.pkgs"
In standalone.conf its default value is "org.jboss.byteman", so that JAVA_OPTS when executing standalone.sh contains -Djboss.modules.system.pkgs=org.jboss.byteman And indeed freshly downloaded WildFly v27.0.0 fails to start with JaCoCo 0.8.8 on J9/Semeru VM. After the addition of "java.lang" to this property -Djboss.modules.system.pkgs=org.jboss.byteman,java.lang it starts successfully.
