Closing attachments on a logger may result in an UnsupportedOperationException ------------------------------------------------------------------------------ Key: LOGMGR-198 URL: https://issues.jboss.org/browse/LOGMGR-198 Project: JBoss Log Manager Issue Type: Bug Reporter: James Perkins Assignee: James Perkins Fix For: 2.1.4.Final In some cases where a logger has a single attachment and the {{close()}} is invoked an {{UnsupportedOperationException}} may be thrown. This is due to the fact that a {{Collections.singletonMap()}} map is used which is immutable.
