Convert a primitive Java type name (e.g., "int", "double", etc.) to a field descriptor (e.g.,
"I", "D", etc.).

@param primitiveName name of the type, in Java format
@return name of the type, in field descriptor format
@throws IllegalArgumentException if primitiveName is not a valid primitive type name
Convert a primitive Java type name ( e . g . int double etc . ) to a field descriptor ( e . g . I D etc . ) .
