[2.0] DDC-176 - Disallow iterate() over fetch-join collections by the means of an exception on parsing the DQL query.

[2.0] DDC-194 - Fixed infinite recursion issue with references and @PostLoad annotation by telling proxy to be loaded before calling EntityPersister->load...

[2.0] DDC-168 - Add test-case that proves that the order of reflFields matters for inserting, which causes problems with caching.

[2.0] DDC-197 - Extended CLOB Test-Case even more with additional update of the string, which still works on OCI8

[2.0] DDC-169 - Stripped case handling since its just a load of complex crap and doesn't solve any problem! Idea: just implement case-insensitivity in the comparator.

[2.0] DDC-169 - Added possibility to control which case mode schema assets are created with in SchemaManager

[2.0] DDC-186 - Fixed DatabaseDriver to work with new Schema abstraction, added functional test-cases for database to yaml convertion.

[2.0] DDC-169 - Changed AbstractPlatform and AbstractSchemaManager and children to accept Table, Index and ForeignKey instances for the respective create*() methods.

[2.0] DDC-169 - Converted introspection queries of all platforms to return Column, Sequence, Index, ForeignKey Schema Instances instead of arrays, heavily pimped Oracle support thereby.

[2.0] - DDC-169 - Completed refactoring of SchemaTool::getCreateSql() to use new DBAL Schema API, several internal optimizations in SchemaTool are now possible. Stripped out shared functionality with getUpdateSql() so that this part of SchemaTool is still completly working with the old API.

[2.0][DDC-164][DDC-165] Fixed. Cleaned up ManyToManyMapping. Cleaned up identifier handling and handling of composite identifiers in some places.

DDC-126 - Make Query, NativeQuery Fluent-Interfaces for all their set Methods, renamed setExpireQueryCache() and setExpireResultCache() to expireQueryCache() and expireResultCache(). Updated UPGRADE_TO_2_0 document accordingly.

DDC-127 - Enhance IterableResult by making it implement the Iterator interface, wrote a unit-test for this scenario, also added some additional tests for special cases in the query api that lead to exceptions.

[2.0][DDC-158] Fixed. Collections did not take snapshots after lazy initialization leading to wrong change sets.

[2.0] Fixed DDC-101, DDC-102 - Ensure defaults for string length and field nullability are handled consistently in both update and create schema commands of SchemaTool.

[2.0] DDC-84 - Add Mysql Platform unittests for incremental changes of the metadata for the schematool update function. Fixed some quirks in the Unit-Test suite alongside, Fixed changes of length in SchemaTool update.
