Its weird that GROK pattern is not parsing the string :

```
org.dozer.config.GlobalSettings.loadGlobalSettings

%{JAVACLASS:class}\.%{JAVAMETHOD:method}

```

I see compile error at [https://grokdebug.herokuapp.com/](https://grokdebug.herokuapp.com/). Please suggest.

`org.dozer.config.GlobalSettings.loadGlobalSettings`

`%{WORD:1}.%{WORD:2}`

```
    {
  "1": [
    [
      "org"
    ]
  ],
  "2": [
    [
      "dozer"
    ]
  ]
}

```

This is not what I am expecting. An output similar to what the below gives.

```
org.dozer.config.GlobalSettings.loadGlobalSettings
%{JAVACLASS:class}\.%{WORD:method}

```

But I think JAVAMETHOD should be the perfect fit but not sure why its not working. Can you see what I mean ?

No the link I found is better. This link is quite generic and pattern matching can get quite specific. But my question remains same why `%{JAVAMETHOD:method}` is not working.
