Description Fares Abdullah CLA 2006-04-04 14:57:47 EDT 
Eclipse 3.2M6 on Windows XP SP2 (eclipse-SDK-3.2M6-win32.zip)
Running on Sun JDK 1.5.0

Add the following two files to a Java project and set its compliance level to 1.3:

public interface MyInterface {
	public void writeToStream();
	public void readFromStream();
}

public abstract class MyClass implements MyInterface {
	public void b() {
	}
	public void a() {
		writeTypeToStream();
	}
	private void writeTypeToStream() {
	}
}


The compiler says that the call to writeTypeToStream() from MyClass.a() is an error because the method doesn't exist. This compiler error goes away if I do things like, but not limited to:
- Delete method b()
- Change the method name, "writeTypeToStream" to something like "c"
- Delete either method from MyInterface
Comment 1 Olivier Thomann CLA 2006-04-04 17:12:59 EDT 
I'll investigate.
Comment 2 Philipe Mulet CLA 2006-04-05 07:54:34 EDT 
Reproduced. Likely a consequence of sorting methods and -target 1.1.
Comment 3 Philipe Mulet CLA 2006-04-05 08:07:45 EDT 
Problem comes from late addition of default abstract methods, which broke the ordering. Fix under testing.
Comment 4 Philipe Mulet CLA 2006-04-05 09:51:29 EDT 
This is a regression over 3.2M5, and only affects -target 1.1 case.
Comment 5 Philipe Mulet CLA 2006-04-05 09:52:31 EDT 
Added LookupTest#test061.
Fixed by re-sorting if necessary when default abstract methods are inserted.
Comment 6 Philipe Mulet CLA 2006-04-05 09:52:44 EDT 
Fixed
Comment 7 Philipe Mulet CLA 2006-04-05 09:54:52 EDT 
Will post a patch on JDT/Core web page.

A patch is available:
See http://www.eclipse.org/jdt/core/r3.2/index.php#UPDATES

Replace the existing jar for jdt/core with this one in the plugins directory of your Eclipse installation directory.

The patch works for me. I no longer see the errors.
