If one extends a generic class with type information already parameterized, the 
resulting class file is rejected by javac for an "undeclared type variable".

Sample:
public class ErrorList extends AbstractList<String> {

  public String get(int index) {
    return "Some string";
  }

  public int size() {
    return 5; // irrelevant
  }

}

public class ListTest {
  
  public static void main(String ... args) {
    System.out.println(ErrorList.class.getName());
  }

}


When compiling both classes with javac and Eclipse, respectively, ListTest 
prints "ErrorList", as expected. When compiling ErrorList with Eclipse and 
ListTest with javac, javac gives the following error message:

ListTest.java:26: cannot access ErrorList
bad class file: ..\bin\ErrorList.class
undeclared type variable: E
Please remove or make sure it appears in the correct subdirectory of the 
classpath.
    System.out.println(ErrorList.class.getName());
                       ^
