| * DESCRIPTION |
| * This test performs checking for |
| * command set: ReferenceType |
| * command: Instances |
| * Test checks that debuggee accept the command packet and |
| * replies with correct reply packet. |
| * Test consists of two compoments: |
| * debugger: instances001 |
| * debuggee: instances001a |
| * Debugger uses nsk.share support classes to launch debuggee |
| * and obtain Transport object, that represents JDWP transport channel. |
| * Also communication channel (IOPipe) is established between |
| * debugger and debuggee to exchange with execution commands. |
| * For maxInstances in [1, 0, Interger.MAX_VALUE] |
| * do |
| * Debugger obtains referenceTypeID for 'nsk.share.jdwp.ReferenceType.instances.instances001.TestClass'. |
| * Then, debugger creates command packet for Instances command with the |
| * found referenceTypeID and maxInstances as an arguments, writes packet to the transport |
| * channel, and waits for a reply packet. |
| * When reply packet is received, debugger parses the packet structure |
| * and extracts number of instances and instance's ids. |
| * Debugger checks that received number of instances is correct: |
| * - if maxInstances=1 only 1 instance should be returned |
| * - if maxInstances=0 or maxInstances=Integer.MAX_VALUE all instances should be returned |
| * done |
| * Also, test performs checks for cases when incorrect data is sent in command. |
| * Following cases are tested: |
| * - create command with maxInstances < 0, expect ILLEGAL_ARGUMENT error |
| * - create command with typeID = -1, expect INVALID_OBJECT error |
| * - create command with threadID instead of referenceTypeID, expect INVALID_CLASS error |
| * Finally, debugger sends debuggee signal to quit, waits for it exits |
| * and exits too with the proper exit code. |
