>Description:
Compiling the attached class with gcj gives:

  $ gcj -c Test.java
  Test.java: In class `Test$1':
  Test.java: In method `paint()':
  Test.java:14: No case for tree code `identifier_node' - java_complete_tree
  $ javac Test.java
  $

The error is also reported for line 15 (Component.this.getSize()) in
the source.

Oskar Liljeblad (osk@hem.passagen.se)

Test.java:
class Component {
	public int getSize() { return 0; }
}

class Canvas extends Component {
	public int getSize() { return 1; }
}

public class Test extends Component {
	public Test() {
		new Canvas() {
			public void paint() {
				int foo1 = getSize();
				int foo2 = Canvas.this.getSize();
				int foo3 = Component.this.getSize();
			}
		};
	}
}

State-Changed-Why:
    This has been fixed in the current cvs. 
    Compiling your test case, I get:
    
    $ gcj -c Component.java 
    Component.java: In class `Test$1':
    Component.java: In method `paint()':
    Component.java:15: Can't use variable `Canvas.this': type `Canvas' isn't an outer type of type `Test$1'.
                          int foo2 = Canvas.this.getSize();
                                     ^
    Component.java:16: Can't use variable `Component.this': type `Component' isn't an outer type of type `Test$1'.
                          int foo3 = Component.this.getSize();
                                     ^
    2 errors
    
    which I believe is the correct error.
