EVALUATION
Will consider synthesizing the classes if they are not available on the bootclasspath.

EVALUATION
Float and Double are required when checking if the unboxing conversion JLS 3, 5.1.7.
The difficulty here is that checking for unboxing is part of the third phase of method resolution, JLS3 15.12.2, and 15.12.2.4, so even overload resolution may indirectly use Float and Double.

EVALUATION
Should work to have empty classes for Float and Double on the bootclasspath for compilation.

EVALUATION
The problem occurs in the unboxing code, where the compiler looks to see if a target type is a subtype of any of the box types.
