These are the differences I recall off the top of my head.
* JDK 1.3 includes JPDA. Thus configuring JDEbug for JDK 1.3 is
somewhat different. The procedure is documented in the beta23
user's guide.
* JDK 1.3 includes a new version of jdb based on JPDA. The new
version breaks the JDE's jdb interface. If you want to use the
JDE with jdb, you have to use the old jdb, which is included, oddly
enough, in JDK 1.3 under the name oldjdb.
* The JDK 1.3 src hierarchy has a slightly different structure. If you
have been including the JDK source code in the debugger source path,
you will have to modify jde-db-source-directories to reflect the new
structure.
* The JDK 1.3 vm is based on hot spot rather than jit technology. Sun
acknowledges that the hotspot compiler causes problems for JPDA. I've
noticed severe performance degredation and problems hitting breakpoints.
The workaround until Sun fixes the problems is to turn off the hotspot
compiler when debugging.
