* jv-lang.h (JAVA_OBJECT_SIZE): Remove. 

(get_java_object_header_size): Add GDBARCH parameter.
	* jv-lang.c (get_java_object_header_size): Add GDBARCH parameter.
	Use it instead of current_gdbarch.
	(evaluate_subexp_java): Replace JAVA_OBJECT_SIZE with call to
	get_java_object_header_size.
	* jv-valprint.c (java_value_print): Likewise.
