concurrency vs. synchronization
which way to go? synchronized? ConcurrentHashMap?
After getting up this morning I thought it would be good to contribute something back to my favourite ORM tool: iBATIS. I picked up IBATIS-508 and tried to create a unit test before applying the patch. Unfortunately I was not able to create one so I wanted to do at least some manual testing in order to find out in which way to fix the issue most efficiently...
