Description

Since version 2.5, when I try to make a "jar-with-dependencies" with the "single" goal, I get a strange mistake.

A file in a dependency (a JDBC driver in my example) is overridden by a file with the same path / name included in a dependency from the JDK / JRE (in my example jre/lib/resources.jar).

In my example, I just add the dependency org.postgresql:postgresql:9.3-1102-jdbc4 to my POM.
Then I package to make a "jar-with-dependencies".
I can find the file META-INF/services/java.sql.Driver in this jar.
But with the version 2.5 of plugin assembly, it contains

• sun.jdbc.odbc.JdbcOdbcDriver (originated from JRE : resources.jar)

and with version 2.4.1 of the plugin, it contains

• org.postgresql.Driver (originated from postgresql-9.3-1102-jdbc4.jar), what I expect

In the previous version (2.4.1) there was no problem.
