AIOOBE in ReferenceExpression.sIsMoreSpecific when saving incomplete statement

### Issue
Saving/compiling a Java file with the following content leads to an `ArrayIndexOutOfBoundsException`:
```java
import java.io.File;

public class JDTIssue {
private void indexOfOfBounds() {
new File("").listFiles(File::isDirectory)
}
}
```
Note that the statement is incomplete, as the semicolon is missing.

### Initial Analysis
`File::listFiles()` is polymorphic and has two 1-argument implementations that accept either a `FilenameFilter` or a `FileFilter`.
These interfaces look as follows:
```java
public interface FilenameFilter {
boolean accept(File dir, String name);
}
public interface FileFilter {
boolean accept(File pathname);
}
```

While searching for the correct method binding (which in this case is the method accepting a `FileFilter`), the method `ReferenceExpression::sIsMoreSpecific()` is executed with type bindings for the two `accept` methods of `FileNameFilter` and `FileFilter`. It compares the parameter lists of both `accept` methods and fails with an AIOOBE due to different sizes of the parameter lists, although the code should only be reached in case the parameter lists have equal length:

The stack when the exception occurs looks as follows:

I can have a look at this issue and provide a PR, but it will take some time until I can address it. So if someone knows that code well and can easily fix this or if you consider this to be more urgent, feel free to take over.
