BeanKeeper (formerly Simple Persistence for Java) is a full featured, powerful object/relational persistence and query library. It has a unique philosophy of simpleness and ease of use: it does not require config files, annotations, code generation, code "enhancing", or any kind of tools to be used. It handles simple Java beans (or POJOs) and its query service returns lists. Despite its simpleness, under the hood the library takes care of all the necessary logic: transaction visibility, result list paging, keys and ids, table creation/modification, class relations, inheritance/polymorphism, case sensitiveness, and much more. It currently supports: Oracle, HSQLDB, MySQL, and PostgreSQL.

Changes:
This release fixes locking and synchronization issues. It fixes a potential memory leak bug in ObjectTracker. Read-only lock support was added to LockManager; now all locks default to read-only locks, while Store operations (save and remove) use write locks. JMX-compatible management beans were added to the API.
