Multiple license headers

Some files, like org.apache.deltaspike.cdise.api.CdiContainer in deltaspike-cdictrl-weld and deltaspike-cdictrl-owb and deltaspike-cdictrl-openejb or org.apache.deltaspike.scheduler.spi.Scheduler have multiple license headers.

Most, if not all of them, got introduced in https://github.com/apache/deltaspike/commit/7df7557
