Should the Java specification support wrapper classes?

I'm revisiting the Java BMI specification. Currently, it's written to use primitive data types for model exchange items. In Java, primitive types are faster and require less memory. They also fit the BMI custom of using basic data types in a language. The drawback is that primitive types can't be represented as a generic type in Java, so they require (for example) a separate get_value method for each type:

public void getValue(String varName, double[] dest);
public void getValue(String varName, int[] dest);
public void getValue(String varName, String[] dest);

Java has wrapper classes for the primitive types (e.g., the Double wrapper for the double primitive). Wrappers are slower and require more memory, but they're likely more often used by Java developers who may not be familiar with BMI, and they support generic types, which simplify the get_value interface:

public <T> void getValue(String varName, T[] dest);

Should the Java BMI specification support both primitive types and wrapper classes?

This would also apply to get_value_at_indices, set_value, and set_value_at_indices.
