| * DESCRIPTION |
| * This test performs checking for |
| * command set: ObjectReference |
| * command: ReferringObjects |
| * Test checks that debuggee accept the command packet and |
| * replies with correct reply packet. |
| * Test consists of two compoments: |
| * debugger: referringObjects001 |
| * debuggee: referringObjects001a |
| * Debuggee during startup initializes static field 'testInstance' with java.lang.Object instance |
| * and creates objects refer to this instance via references with types which should be supported |
| * by command ObjectReference.ReferringObjects: |
| * - strong reference |
| * - soft reference |
| * - weak reference |
| * - phantom reference |
| * 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 maxReferrers in [1, 0, Interger.MAX_VALUE] |
| * do |
| * Debugger obtains objectID for instance assigned to the debuggee's static field 'testInstance'. |
| * Then, debugger creates command packet for ReferringObjects command with the |
| * found objectID and maxReferrers 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 referring objects and referring objects ids. |
| * Debugger checks that received number of referring objects is correct: |
| * - if maxReferrers=1 only 1 referring object should be returned |
| * - if maxReferrers=0 or maxReferrers=Integer.MAX_VALUE all referring objects should be returned |
| * done |
| * Also, test performs checks for cases when incorrect data is sent in command. |
| * Following cases are tested: |
| * - create command with maxReferrers=-1, expect ILLEGAL_ARGUMENT error |
| * - create command with objectID = -1, expect INVALID_OBJECT error |
| * Finally, debugger sends debuggee signal to quit, waits for it exits |
| * and exits too with the proper exit code. |
