Description
Removing String/StringBuffer sharing will be necessary for correctness in light of the new memory model, it will reduce the wasted memory caused by oversized backing arrays for Strings, and it will allow the introduction of an unsynchronized version of StringBuffer. Other VM improvements may also be enabled by this change.
