在Tapestry（5.0）中，当我尝试重新编译我在java类中的更改时，我会得到一个弹出窗口
Hot Swap Failed
abc.xyz : hierarchy changes not implemented
abc.xyz : Operation not supported by the VM
AFAIK这应该可行，因此我最终重新启动调试会话，这需要相当多的时间。 对此有何帮助？

You see this warning, because IntelliJ is failing to hot swap the classes, because, as the message says: VM doesn't support this operation for your changes.
What Tapestry is doing is actually not a hot swap, it's called "Live Class Reloading".
In short: instead of updating existing classes and objects inside VM (what hot swap is doing), Tapestry throws old classes away with all their state, and loads/initialises them again using a custom class loader. It can only do this for its managed classes: page/component/mixin classes and IoC service implementations that are registered using service interface. Everything else can only be reloaded with a hot swap if it's implemented by a VM.
You can read more details about Live Class Reloading in official documentation .
