Hi Gabriel, Thank you for your help. I will refactor the rest of other tests like that as well.

I've grabbed the profiler and ran the test suite, then I got one of the most time/mem consuming tests, FeatureChainingTest and profiled it alone. Aside, I actually doubt it is one of the most offending ones, but just where the profiler went crazy with 512m heap when running the test suite, which makes me think there're some serious memory leaks at the feature type registry or close to it. Still, I was able to reduce the needs of FetureChainingTest from 255M of Heap and 27 seconds build time to 102M Heap and 9.2 seconds build time. That is achieved by the attached patch, which converts the test to JUnit 4 and uses @BeforeClass and @AfterClass methods to set up the needed DataAccesses once for the whole suite. I guess we can do the same for most of the test suites, except for the few that actually assert the loading of a configuration. But other than those, they should be all read-only tests, since app-schema support is read only after all, so we could migrate them to one time loading. That said, I'd be glad in keep investigating the source of the leaks AND in helping redesign the schema parser so it does not parses ALL the types and top level elements in the xsd schemas but only the ones needed by the mappings. Those two improvements I'm pretty sure will provide a substantial difference in startup time and memory requirements for the module. So, ok to commit the patch to FeatureChainingTest? Rini do you want to go through the rest of them and refactor like I did for this one?
