Description

Missing inner class table entry is causing class resolution issues for older Eclipse IDE versions (2018-09 and earlier).

Consider the following:

class One {
  static class Two {
    static class Three {
    }
  }
}

When compiled by groovyc, the inner class table for Three is like this:

  Inner classes:
    [inner class info: #2 One$Two$Three, outer class info: #56 One$Two
     inner name: #143 Three, accessflags: 9 public static]

When compiled by javac, the inner class table for Three is like this:

  Inner classes:
    [inner class info: #12 One$Two, outer class info: #22 One
     inner name: #13 Two, accessflags: 9 public static],
    [inner class info: #2 One$Two$Three, outer class info: #12 One$Two
     inner name: #15 Three, accessflags: 9 public static]

The extra entry that refers to the direct outer class is present for Two under groovyc, but not for Three (the twice nested class).
