------------------------------------------
This is also an issue for Spring Framework META-INF files (spring.handlers, spring.schemas)

> Service provider configuration files are text files that define what "service providers" are available for a specific interface. These files are normally stored in /META-INF/services/ and are named after the interface that is implemented (e.g. "java.io.spi.CharCodec"). See for more info:
> http://java.sun.com/j2se/1.5.0/docs/guide/jar/jar.html#Service%20Provider
> and
> http://java.sun.com/javase/6/docs/api/java/util/ServiceLoader.html
> Building a onejar from a multi-module project where multiple modules have similarly named services files results in a jar-file that includes just one of the service files. As a result, just the providers that are mentioned in that file are seen by applications running from the onejar, providers that were mentioned in the other service files are not. To fix this, service files with identical names should simply be concatenated (making sure that there's a newline between the contents of each service file).
