Use a better mechanism to parse config files
--------------------------------------------

                 Key: ISPN-1065
                 URL: https://issues.jboss.org/browse/ISPN-1065
             Project: Infinispan
          Issue Type: Enhancement
          Components: Configuration
    Affects Versions: 4.2.1.FINAL
            Reporter: Manik Surtani
            Assignee: Manik Surtani
             Fix For: 5.1.0.BETA1, 5.1.0.Final


The current codebase heavily relies on JAXB to:

1.  Generate a XSD schema from a Configuration bean
2.  Generate a parser to use with an XML configuration

This is known to be slow, and can significantly add to start up time:

We did some analysis of our AS6 descriptor code which was using JAXB (800ms), compared to straight stax (10ms)

A possible solution could be to still use JAXB to generate the schema, but to also write a Maven plugin which would generate a STAX parser based on the XSD schema and Configuration bean at build time.  Infinispan would then use this STAX parser rather than a JAXB generated parser, which would be a lot faster.
