Description Janis Krumins CLA 2006-01-10 16:30:20 EST 
This error occurs intermittently only on files which include multiple nested anonymous inner classes. For example, on this one:

package test;

public class Test {
	public void qwertyuiopasdfghjklzxcvbnmQwertyuiopasdfghjklzxcvbnmQwertyuiopasdfghjklzxcvbnmQwertyuiopasdfghjklzxcvbnm(Runnable runnable) {
		runnable.run();
	}
	
	public void abcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyz(Runnable runnable) {
		runnable.run();
	}

	public static void main(String[] args) {
		new Test().qwertyuiopasdfghjklzxcvbnmQwertyuiopasdfghjklzxcvbnmQwertyuiopasdfghjklzxcvbnmQwertyuiopasdfghjklzxcvbnm(new Runnable() {
			public void run() {
				new Test().abcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyz(
				new Runnable() {
					public void run() {
						System.out.println("Hello world.");
					}
				});
			}
		});
	}
	
}

The long method names may or may not be relevant - I am not certain whether they increase the likelihood of this occurring, I'm thinking that they don't.

The only relevant entry in the log seems to be the following:

Comment 1 Janis Krumins CLA 2006-01-10 16:39:02 EST 
a) The file with the inner classes needs to be touched/modified for the bug to exhibit itself upon the auto-rebuild.
b) Just repeated it with short file names, sorry about the long version:

package test;

public class Test {
	public void b(Runnable runnable) {
		runnable.run();
	}
	
	public void a(Runnable runnable) {
		runnable.run();
	}

	public static void main(String[] args) {
		new Test().b(new Runnable() {
			public void run() {
				new Test().a(
				new Runnable() {
					public void run() {
						System.out.println("Hello world.");
					}
				});
			}
		});
	}
	
}

c) Looks like it exhibits itself after the project was rebuilt using the standard Java 1.5 JDK (invoked from an "ant" script).
Comment 2 Olivier Thomann CLA 2006-10-10 15:39:59 EDT 
Do you still get it with 3.2.1 or 3.3 integration builds?
Closing as REMIND.
Please reopen if you still get it.
Comment 3 Denis Roy CLA 2009-08-30 02:08:43 EDT 
As of now 'LATER' and 'REMIND' resolutions are no longer supported.
Please reopen this bug if it is still valid for you.
