[configuration] Dependencies after switch to 1.4

[Oliver Heger <ol...@oliver-heger.de>]

In order to change the minimum required JDK to 1.4 I modified pom.xml. I 
was hoping to get rid of all the XML-related dependencies, but obviously 
this is not so easy.

When dropping the Xerces-dependency I get a bunch of test failures:
- Many of them are caused by tests for DatabaseConfiguration. Here 
dbunit cannot resolve the DTD in the dataset file. This can be solved by 
simply removing the reference to the DTD.
- The major problem is caused by tests that require advanced validation 
features, e.g. schema validation. This is not supported by the parser 
shipped with Java 1.4.

Because of the latter point I think we are forced to keep the 
Xerces-dependency (with test scope). Unfortunately, this also demands 
the dependency to XML-APIs - otherwise I get NoClassDefFound errors.

Or is there an alternative?

At least the dependency to Xalan can be dropped. I wonder whether this 
has some impact on GUMP which has still trouble with building 
[configuration].

Agreed, it is probably not worth the effort. So it is a matter of 
documentation on our dependencies page. There has to be a statement that 
Xerces is required on JDK 1.4 for schema validation.

I believe this could be addressed by changing the pom to only include Xerces and XML-APIs when compiling with JDK 5+ with a desired target of JDK 5+ and then having the unit tests that use validation only run when Java 5+ is enabled. However, this seems like a lot of work for little benefit since Xerces and XML-APIs already have test scope so they won't be brought in to a user's project unless they wants them.

With 1.5 the Xerces dependency is no more needed.

There is some work going on for a Configuration 2.0 version which uses 
Java 1.5. We have a branch for this project. So the idea is that 2.0 
depends on Java 1.5 while the 1.x series remains on 1.4. Once 2.0 is 
released, there should only be bug-fix releases for 1.x. However, I fear 
there is still much work to do before 2.0 can be published.

What would a dependency of 1.5 mean with regards to the Xerces dependency?

You depend on Lang/Collections, and both are 1.5 dependent for their
next version.
