HotSpot Performance Engine added to Solaris JDK 1.2.2 on Athena   5/22/00
 
HotSpot has been added to the Sun/Solaris Java Development Kit 1.2.2
on Athena (the current Athena default). HotSpot is a specialized Java
compiler designed to improve Java runtime performance by a variety of
techniques. It is used by default and does not require users to change
invocation of the JDK tools. If you want to use the original form of
the JDK tools, you should invoke them with the "-classic" command-line
switch, which must be the first switch on the command line. For
example, to compile an application MyApp.java with HotSpot, do:

	javac MyApp.java

or without it, do:

	javac -classic MyApp.java

In similar fashion, you can do things like:

	appletviewer -classic MyApplet.htm 
	javac -classic MyApp.java 

to use the original form of the tools without invoking
HotSpot. Documentation is available from Sun at:

http://java.sun.com/products/hotspot/1.0/README-Sparc.html

We do not have information about HotSpot availability on other platforms
at this time.
