我正在开发一个跨平台的引导程序，它在OSX/Linux上运行正常，但在Windows上返回以下错误信息：
错误：无法创建Java虚拟机。 错误：发生致命异常。程序将退出。 未识别选项：-cp C:/myapp/realm/bin/Launcher.jar;C:/myapp/_jvm/jre/../lib/tools.jar;C:/myapp/realm/shared/lib/jetty-util-8.1.4.v20120524.jar
如果我打印出ProcessBuilder参数列表并在命令行上运行这些参数，它将成功运行。命令应该是：

我尝试在类路径周围放置引号，使用双斜杠等等，但都无济于事。希望能得到帮助...下面是代码：
String mainClass = args[0];
String propFile = args[1];
FileInputStream fis =new FileInputStream(propFile);
BufferedReader br = new BufferedReader(new InputStreamReader(fis));
String line = null;
ArrayList<String> argList = new ArrayList<String>();
while((line = br.readLine()) != null){
if(line.startsWith("#"))
continue;
String trimmedLine = line.trim();
if(trimmedLine.isEmpty())
continue;
Matcher m = p.matcher(trimmedLine);
StringBuffer sb = new StringBuffer();
while(m.find()){
String content = m.group(1);
String envContent = System.getenv(content);
if(envContent == null || envContent.isEmpty())
envContent = System.getProperty(content);
m.appendReplacement(sb, envContent);
}
m.appendTail(sb);
if(!sb.toString().startsWith("\"-") && !sb.toString().startsWith("-") && argList.size() > 0)
argList.set(argList.size()-1, argList.get(argList.size()-1)+File.pathSeparator+sb.toString());
else argList.add(sb.toString());
}
ArrayList<String> cmdList = new ArrayList<String>();
cmdList.add(System.getenv("JAVA_HOME") + File.separator + "bin" + File.separator + "java");
cmdList.addAll(argList);
cmdList.add(mainClass);
System.out.println(cmdList.toString());
ProcessBuilder pb = new ProcessBuilder(cmdList);
new ProcessBuilder(line);
File f = new File(System.getenv("MY_DIR") + File.separator + "logs" +File.separator + "provider-console.log");
if(!f.exists())
f.createNewFile();
pb.redirectErrorStream(true);
pb.redirectOutput(f);
pb.directory(new File(System.getenv("MY_DIR") + File.separator + "bin"));
Process p = pb.start();
这是toStringed cmdList:
注：cmdList指的是命令列表，toStringed指的是将其转换成字符串形式。[C:/myapp/_jvm/jre\bin\java, -javaagent:C:/myapp/realm/bin/spring-agent.jar, -Xmx256m, -Xms200m, -Xss128k, -XX:+UseBiasedLocking, -XX:+UseNUMA, -cp C:/myapp/realm/bin/Launcher.jar;C:/myapp/_jvm/jre/../lib/tools.jar;C:/myapp/realm/shared/lib/jetty-util-8.1.4.v20120524.jar, -DprocessType=realm, -Dcert.framework.license=C:/myapp/realm/license/jericho.license, -Djava.security.policy=C:/myapp/realm/security/java.policy, -Djava.security.properties=C:/myapp/realm/security/java.security, -Djava.security.auth.login.config=C:/myapp/realm/security/jaas.conf, -Drealm.home=C:/myapp/realm, -Duser.dir=C:/myapp/realm/bin, -Djava.endorsed.dirs=C:/myapp/realm/endorsed;C:/myapp/_jvm/jre/lib/endorsed, -Djava.ext.dirs=C:/myapp/realm/ext;C:/myapp/_jvm/jre/lib/ext, -Dlog4j.configuration=file:C:/myapp/realm/conf/log4j.properties, -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger, com.myapp.launcher.ProviderLauncher]
