[Java APIView] Method signature is incorrectly rendered with inline comment text

Bad code snippet:
```java
public static SecretServiceVersion getLatest(// returns V7_6 )
```

What it should do:
APIView should not render a valid Java method signature as if it contains an inline comment inside the parameter list. The text `// returns V7_6` is not a real comment in the source and is misleadingly shown as part of the code snippet due to a parser/rendering issue.

Good code snippet:
```java
public static SecretServiceVersion getLatest() {
return V7_6;
}
```

Start by reproducing the Bad code snippet in the APIView Java parsing and rendering flow, then compare it with the Good snippet. Trace how the method signature is tokenized and displayed; done means the valid signature is rendered without the `// returns V7_6` text.
