* jv-lang.c (jv_type_objfile_data_key, dynamics_objfile)
(class_symtab): Remove. (jv_dynamics_progspace_key): New global. (jv_per_objfile_free): Reset program space data. Update assert. Don't clear globals. (get_dynamics_objfile): Use and set program space data. (get_java_class_symtab): Use get_dynamics_objfile. (add_class_symbol): Likewise. (java_link_class_type): Likewise. (java_object_type, jv_clear_object_type, set_java_object_type): Remove. (get_java_object_type): Update. Don't cache result. (is_object_type): Don't call set_java_object_type. (_initialize_java_language): Don't set jv_type_objfile_data_key; initialize jv_dynamics_progspace_key.
