If destination class exists - IDE freezes

[Jeansen]

Generating a class that already exists in a project make the latest Inellij IDEA freeze.

Oh, Thanks for feed back, will check it later

I checked local on MacOS, it doesn't freeze when generate a exists class name file here, is that convenient to record a video to show the problem?

[Jeansen]

Well, there's not much to record. After I click the generate button, the dialog simply disappears and I cannot do much. Looking at the log, I see the following. I cleared the log before, so it is only shown what happens when I use the plugin to create a file and do the same again. Also, my CPU has extreme loads after that. Only way is to hard kill the process.

How big is your JSON, is it too much content in the JSON?

[Jeansen]

No, it is very simple.

{
  "cluster": {
    "masterNodes": [
      {
        "id": 0,
        "status": "provisioned",
        "snapshots": [
          1670448150
        ]
      }
    ],
    "workerNodes": [
      {
        "id": 1,
        "status": "provisioned",
        "snapshots": [
          1670448151
        ]
      }
    ]
  }
}

So, I tried around a bit more. When I use the default settings (after plugin install) and try to generate a class with the same name that already exists, new files appear with an X appended. For instance, If a class 'Clsuter.kt' already existes, a class 'ClusterX.kt' would be created. Running the plugin again and telling it to generate the class 'Cluster' would create a class 'ClusterXX.kt', and so forth.

The IDE freezes in my case, where I use the following settings:

If I generate a class, e.g. 'Cluster', with these settings and that class already exists, then the IDE freezes and I see the output as shown in the log excerpt above.

I will check it later
