so i think most java debuggers, even jdb, are capable of reloading
classes aren't they?
i haven't tried your example, but in the cdt, you use
the .redefineClasses method to reload a java class
For example, I can hack on one of the classes in clojure compiler and
reload it, without restarting, like so:
(.redefineClasses
(vm)
{(first (find-classes #"clojure.lang.Compiler\$DefExpr\$Parser"))
(to-byte-array
(java.io.File.
"/Users/georgejahad/incoming/clojure/classes/clojure/lang/Compiler
$DefExpr$Parser.class"))})
is that what you are talking about, or am i missing something?
