/**
 * The raw invoker provides a raw (fast) access invoke operations, get attribute values, and set
 * attribute values on a GBean.  This class should only be use by GBean proxy generators or carefully
 * crafted container code, because this class maintains a hard reference to a gbeanInstance which has a huge
 * potential for memory leaks.  USE WITH CAUTION
