the class BytecodeNode method allocateMultiArray.

// endregion Class/Method/Field resolution
// region Instance/array allocation

    putObject(frame, top - allocatedDimensions, getInterpreterToVM().newMultiArray(((ArrayKlass) klass).getComponentType(), dimensions));
    // Does not include the created (pushed) array.
    return -allocatedDimensions;
