I've never seen anything like this.  Were there any other errors further up?  

In general nothing should ever fail like this so you should put in a JIRA case.  You might want to turn up logging levels (either by
editing  install-log.xml or by pointing INSTALL_LOG_FILE to a suitable logback file.).
