The JBoss server console hangs during the startup process.
Solution:
Step 1: Go to the %JBOSS_HOME%\standalone\deployments\ folder and delete any file with a .failed extension, for example, appeonserver.ear.failed.
Step 2: Clean up the temporary files under the %JBOSS_HOME%\standalone\tmp\ folder.
Step 3: Restart JBoss server.
