Summary: DrJava won't start up on Windows XP with Java 1.3

Initial Comment:
Are we still supporting Java 1.3? drjava-20030216 works 
fine on OS X under 1.3, but I can't even start it up on 
Windows XP. It looks like the problem is with class file 
versions.

If I try to start it with javaw, it warns me that it can't find 
the debugger, and then the splashscreen hangs. 

If I try to start it via the command-line with Cygwin, I get 
an unexpected exception. Since this only happens 
under Java 1.3, I can't cut-and-paste the entire stack 
trace into Internet Explorer, but the error is:

java.lang.UnsupportedClassVersionError:com.sun.jdi.Boo
tstrap (Unsupported major.minor version 48).

Our code is at the base of the stack trace. The last 
method of ours that's called is 
edu.rice.cs.drjava.DrJava.classLoadersCanFindDebugger
(DrJava.java:415).

I'm sorry I can't provide the entire stack trace. Let me 
know if more information would be helpful.

BTW, I am able to start it from the command-line with 
Cygwin after doing a pickjava 1.4.

Even if we don't want to support 1.3 anymore, we might 
want to consider trying to exit more gracefully, since 
there are still a lot of 1.3 JVMs out there...
