JDK-4990346 - wrapper static factories fail to cache as required
Description
The boxed primitive types should cache commonly-requested values for use in
the static factories.
Comments
EVALUATION A reasonable optimization to consider. Presumably small integers will be the most important to box. Benchmarks showing value distribution would be helpful. ###@###.### 2003-10-23 Such caches were implemented to adhere to the autoboxing specification; see bug 4990346 "wrapper static factories fail to cache as required." ###@###.### 2004-07-27
