Building OpenJDK: imported nested, nested private class not visible higher up in hierarchy

I am working on building OpenJDK JDK8u using ecj (for speed). This bug occurs building:

`langtools\src\share\classes\com\sun\tools\javac\comp\LambdaToMethod.java`

```
4. ERROR in D:\ikvm\ext\openjdk\langtools\src\share\classes\com\sun\tools\javac\comp\LambdaToMethod.java (at line 93)
private Map> contextMap;
^^^^^^^^^^^^^^^^^^
The type TranslationContext is not visible
```

The `TranslationContext` type is nested within a nested class, in the same file, which is imported at the top of the file by wildcard.

`import com.sun.tools.javac.comp.LambdaToMethod.LambdaAnalyzerPreprocessor.*;`

Simply changing the referencing code to `LambdaAnalyzerPreprocessor.TranslationContext>` solves the issue. Basically, it looks to me, like the top-file import just isn't working. It is pretty odd code. But there it is.

This is on ecj-4.20

Start with langtools/src/share/classes/com/sun/tools/javac/comp/LambdaToMethod.java, especially the wildcard import of LambdaAnalyzerPreprocessor.* and the TranslationContext reference around line 93. Reproduce the JDK8u build with ecj-4.20, then compare the wildcard reference with the qualified form mentioned in the report. Done means the affected build proceeds without the visibility error.
