Description Alex Blewitt CLA 2009-07-29 16:48:01 EDT 
The following code generates an error with Sun's javac but Eclipse JDT compiles it without reporting an error:

--- 8< ---
import java.util.Collection;

public class CompilerBug {
	public int foo(Collection bar) { return 0; }
	public double foo(Collection<String> bar) {return 0; }
}
--- 8< ---
alblue:tmp alex$ javac CompilerBug.java 
CompilerBug.java:5: foo(java.util.Collection) is already defined in CompilerBug
	public double foo(Collection<String> bar) {return 0; }
	              ^
1 error

Note that making the first method a generic type (like Collection<Double>) results in it compiling fine in both Eclipse and javac.
