I took a quick look at this. I think they're only about half a dozen
places where Cobertura uses 1.4 methods, mostly related to the
java.util.regex package. Classes include

XMLReport
JavaToHTML
Main
CoverageReportTask
MethodInstrumenter
CommonMatchingTask

There's also one use of Character.toString().

I don't think these would be too difficult to remove. If the regular
expressions are simple enough, we could write the code to do the
replacements manually. If not, we could fall back on something like the
ORO regex library instead of java.util.regex. Hmm, looking at a couple
of the places where it's used regular expressions do seem to be a pretty
fundamental part of the internals so I suspect using a 3rd party regex
library would be the preferred option.

It might be a good idea then to have separate 1.3 and 1.4 distros so the
1.4 version doesn't have to drag along an extra regex library. This can
be organized in the ant build file easily enough. JDOM does something
like this to run in both 1.1 with com.sun.util collection classes and in
1.2 and later with java.util collection classes.
