Description

When the pom is encoded in a charset different than the one declared in the xml header (UTF8 by default) and containing an special char (ó or something like that), under Sun's JDK there's no error but under IBM JDK it crashes with
sun.io.MalformedInputException

It'd be good if we could check first the encoding or capture the exception and show an error message instead.
