No, actually I dont.

But - maybe you know that you can compile (1.4 and 1.5) your source
with parameters
'src' and 'target', where src is the Java source version and target is
the target supported Java version.

In your case:
compile the source (in java 1.5) to target 1.4 or src and target both
for 1.4, then the
compiler ought to give you info on what to change.
In Eclipse (and others?) editor you can compile in runtime, which makes
the job easier.

It is not automatically writing your code, but the job gets done.

Good luck

Stripping generics should be easy.  just yank stuff <xxx>.  Everything
still works just the same because of type erasure.

To get rid of Enum is harder. You would have to create an Eunum class
that behaved much like Sun's.  You would then decompile the 1.5 code
with JAD and use the result as 1.4 code.

I have heard people mention some tool Nostalgia, TheGoodOldDays --
something like that.  Someone will surely mention it, that lets you
retrofit 1.5 code to 1.4 JVMs.
