J2SE Code Names This little list helps to make sense of those J2SE BugIDs which reference J2SE code names. VERSION CODE NAME   RELEASE DATE JDK 1.1.4 Sparkler Sept 12, 1997 JDK 1.1.5 Pumpkin Dec 3, 1997 JDK 1.1.6 Abigail April 24, 1998 JDK 1.1.7 Brutus Sept 28, 1998 JDK 1.1.8 Chelsea April 8, 1999 J2SE 1.2 Playground Dec 4, 1998 J2SE 1.2.1 (none) March 30, 1999 J2SE 1.2.2 Cricket July 8, 1999 J2SE 1.3 Kestrel May 8, 2000 J2SE 1.3.1 Ladybird May 17, 2001 J2SE 1.4.0 Merlin Feb 13, 2002 J2SE 1.4.1 Hopper Sept 16, 2002 J2SE 1.4.2 Mantis June 26, 2003 Future Releases J2SE 1.5.0 Tiger Not yet released J2SE 1.5.1 Dragonfly (dragon) Not yet released J2SE 1.6.0 Mustang Not yet released 11:42:02 PM     MaxPermSize and how it relates to the overall heap Many people have asked if the MaxPermSize value is a part of the overall -Xmx heap setting or additional to it. There is a GC document on the Sun website which is causing some confusion due to a somewhat vague explanation and an errant diagram. The more I look at this document, the more I think the original author has made a subtle mistake in describing -Xmx as it relates to the PermSize and MaxPermSize. 4:23:09 PM
