64 * First, this file contains the VM-related functions needed by native | |
65 * libraries in the standard Java API. For example, the java.lang.Object | |

67 * | |
68 * Second, this file contains the functions and constant definitions | |
69 * needed by the byte code verifier and class file format checker. | |
70 * These functions allow the verifier and format checker to be written | |
71 * in a VM-independent way. | |
72 * | |
73 * Third, this file contains various I/O and nerwork operations needed | |
74 * by the standard Java I/O and network APIs. | |

81 * | |
82 * 2. There is a change in the contract between VM and Java classes. | |
