> There are potentially overflowing expressions in org.wildfly.security.permission.LongNameSetPermissionCollection in {{getBitsForName}} method. Expressions {{1 << nameEnumeration.size()}} and {{1 << nameEnumeration.indexOf(name)}} are evaluated as integer but assigned to {{bits}} variable which is long. It can be avoided by casting {{1}} to long.
