The pipe 50 * is used in bi-directional way by sending and receiving special commands between 51 * the debugger and debuggee for synchronization 52 * In case of error the test produces the exit code 97 and a corresponding error 53 * message(s). Otherwise, the test is passed and produces the exit code 95 and 54 * no message. 55 * COMMENTS: 56 * 4883502 TEST_BUG: waiting Threads testcases not predictable 57 * 58 * @library /vmTestbase 59 * /test/lib 60 * @run driver jdk.test.lib.FileInstaller . . 61 * @build nsk.jdi.ObjectReference.waitingThreads.waitingthreads002 62 * nsk.jdi.ObjectReference.waitingThreads.waitingthreads002a 63 * @run main/othervm PropertyResolvingWrapper 64 * nsk.jdi.ObjectReference.waitingThreads.waitingthreads002 65 * -verbose 66 * -arch=${os.family}-${os.simpleArch} 67 * -waittime=5 68 * -debugee.vmkind=java 69 * -transport.address=dynamic 70 * "-debugee.vmkeys=${test.vm.opts} ${test.java.opts}" 71 */ 72 73
