A method I've used in the past to switch between backport-util and java5
is to create two sets of subclasses. One set of subclasses inherits
from backport-util, the other from java5. Each set of subclasses exists
in the same package, but the code is kept in distinct source
directories. The rest of the code in the project is written to use
these subclasses. Then I use profiles in the maven pom to select the
best set of subclasses based on the jvm used to build or a property.
A quick search of MINA code shows that there are only 14 classes that
are actually used in backport-util

Good idea; A script that forks instantly, deploys the jar, and wipe the
forked source code would be a cleaner option.
