There is a family of options such as -XX:OnOutOfMemoryError, -XX:+HeapDumpOnOutOfMemoryError in Oracle Java. The first one is used to launch an external script in case of OOM. Doing anything from Java rarely works in case of an OOM error, especially a "PermGen" OOM. (You have a bit more luck with your "Java heap space" one). See http://markmail.org/message/rr26epg4oap4syus "Notification strategy for OutOfMemoryError" thread from about a year ago.
