--------------------------------------------------------
I have the following link
http://en.wikipedia.org/wiki/Comparison_of_backporting_tools
http://retrotranslator.sourceforge.net/
talks about retrotranslator and "How to produce a jar file compatible with Java 1.4?"
We are also using the same
backport-util-concurrent-3.0.jar
retrotranslator-runtime-1.2.1.jar
to support transparent bytecode enhancement which allows to develop against 1.5 and seamlessly deploy on 1.4.
Wont it support for covariant return types?

Why it is not able to work on covariant return types?
