What exactly do you mean by 1.5-requiring code? Do you mean
1. the parts of the class-library that were introduced by Java 1.5 or
2. the new language features?
As for point 1, I don't think that these classes will be in the new 
release (but I might be completely wrong, I have no idea).
If you're talking about the language features and, as you have said 
you're using another bytecode compiler than gcj anyway, there's no need 
to wait for the new release. Just compile your .java to .class files 
with a bytecode compiler that understands these language features. They 
will be disappeared in the .class files (backwards compatibility issues, 
I guess). I'm doing that for a long time now and these language features 
all work:
- generics
- autoboxing/unboxing
- extended for loops
- static imports
- varargs
- enumerations
The only thing I can't test because I don't know how are annotations.
