运行时类创建的线程冻结，MineCraft，JavaFX控制器

Question

我正在通过运行时创建线程，一段时间后，我的线程冻结了。

代码：

 @Override
public MineCraftProcess launch(@NotNull LaunchParameters args) throws Exception {
    this.command.append(" ").append(args.build());

    Process process = Runtime.getRuntime().exec(command.toString());

    return new MineCraftProcess(this, process);
}

命令：
