  Java Development Kit upgrade to release 1.2.2 (SGI) and 1.3.0 (Linux, Sun)  
 
We have installed JDK 1.2.2 (production release) for SGI and 1.3.0
(beta) for Sun and 1.3.0 (production release) for Linux. The Linux release
is a new port just released by IBM. We expect to make these the Athena
defaults within about 2 weeks.

These are the latest available releases as of this writing.

To run these now do "add java" (SGI, Linux) or "add -f java" (Sun)
followed by a JDK command immediately followed by a "-ver" switch, i.e. like:

javac -ver 1.3.0 myfile.java (Sun, Linux) 
javac -ver 1.2.2 myfile.java (SGI)

(if you use any other command-line switches, they must follow the "-ver"
 switch).

After these become the default, the "-ver" switch can be dropped.

Documentation in html format is available starting from

http://web.mit.edu/java_v1.2.2/www/sgiindex.html (SGI-specific 1.2.2 docs)
 
Older JDK versions are still available and can be used by adding the 
appropriate version switch in the run command (i.e. "add java; 
java -ver 1.1.6 myfile" to use JDK 1.1.6 for Linux or SGI, or 
"add -f java; java -ver 1.1.6 myfile" for Sun) (and so on)
