Unnecessary folding of method use for methods starting with word  'issue'.

I implemented and used method `issueCertificate()`.
I guess the plugin thought it was a getter for some boolean and this line:

```
Certificate certificate = issueCertificate();
```

got folded to:

```
Certificate certificate = sueCertificate;
```

Probably a check for camelCase after prefix `is` would be sufficient.

It's not a big problem but it's annoying :)
