This issue has been observed because of not having protocol.jar in classpath while starting jboss server. You can follow this workaround to fix the issue.
Copy %DYNAMO_HOME%/DAS/lib/protocol.jar
to C:\lib
or any folder that is easily accessible to you.
Open Standalone.conf.bat
and add following line in the file.
set "JAVA_OPTS=%JAVA_OPTS% -Djava.endorsed.dirs=C:\lib"
Open the Jboss server after the above update is done. The error will be resolved.
