StringIndexOutOfBoundsException when deploying applications with 3 characters or less

Deploy an archive (in my case programmatically using MainDeployer, but should not matter), whose name has 3 characters or less.
org.jboss.as.naming.javaee.NamingJavaEEApplicationInformer tries to truncate the last 4 characters, which results in
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
