JIRA: https://jira.spring.io/browse/INT-4048
The semantics of the locks are the same as for the default lock
registry (they have to be unlocked by the same thread that
locked them).
Updates from feedback
Add interface for JdbcClient so transactions can bind to proxy
Fix typo in exception message
Fix drop script
JdbcClient -> LockRepository
Make lock() contract more like native Lock
Make lockInterruptibly throw InterruptedException more
Delete all expired locks, not just the ones that we own
INT-4048: Polishing
* `DefaultLockRepository`: replace `prefix` only once in the `afterPropertiesSet()`
* Add JavaDocs to the `DefaultLockRepository`
* `JdbcLockRegistry`: add `Thread.sleep(100)` to lock loops do not request DB so often like in case of clean `while(true)`
* `JdbcLockRegistry`: implement more robust `tryLock(long time, TimeUnit unit)`. The logic mostly copied from `RedisLockRegistry`
* Add `testExclusiveAccess()` to be sure that JDBC locks have exclusive access to the data sequence
Document `JdbcLockRegistry`
Upgrade to SF-4.3 GA
