示例1: runTest

public static boolean runTest() throws Exception {
ProcessBuilder pb = ProcessTools.createJavaProcessBuilder(
"-XX:+UnlockDiagnosticVMOptions", "-XX:+PauseAtStartup", "AttachWithStalePidFileTarget");
Process target = pb.start();
Path pidFile = null;
try {
int pid = getUnixProcessId(target);
// create the stale .java_pid file. use hard-coded /tmp path as in th VM
pidFile = createJavaPidFile(pid);
if(pidFile == null) {
return false;
}
// wait for vm.paused file to be created and delete it once we find it.
waitForAndResumeVM(pid);
// unfortunately there's no reliable way to know the VM is ready to receive the
// attach request so we have to do an arbitrary sleep.
