Description

While profiling the memory usage of our application, I noticed some unneccesary boxing and unboxing operations in Jackrabbit.

I propose to remove these with the provided patch in order to make the code more readable and reduce the amount of allocated (boxed) objects.

The patch can be found here: https://github.com/apache/jackrabbit-oak/pull/203
