[JBCACHE-964] Work committed:- Transforming Cache Loaders implemented and unit tests provided- migration folder structure. See JIRA.- build.xml modified to compile, jar, create manifest for migration jarand also added examples and migration jar to distros.- example created and tested; it includes readme.txt with details of theexample and how to run it.Still TODO:- Unit tests for transforming cache loaders need to run from build.xml- Documentation for transforming cache loaders in users guide, what arethey, when to use them,...etc.- Fix JBCACHE-877 that occurrs when unzipping JBossCache-core-2.0.0.BETA2.zipand running the examples. Workaround is to bring trove.jar into its lib.- Get examples/cacheloader-migration/build.sh working- Move JDBCCacheLoaderOld to the migration side. It's not that straightforward due to classes in/src having dependencies on it. Needs further study.
