Eclipse 3.6 compiles the following code without any
errors

interface List<E> {}
interface I {}

public class X {
    <T extends I> void main(List<T> clazz, List<X> xList) {
        boolean b = clazz == xList ||
		    xList == clazz;
    }
}

while javac complains:

X.java:6: incomparable types: List<T> and List<X>
        boolean b = clazz == xList ||
                          ^
X.java:7: incomparable types: List<X> and List<T>
                    xList == clazz;
                          ^
2 errors

C:\jtests>rem C:\ibm-java2-sdk-50-win-i386\bin\javac.exe -Xlint:unchecked -Xlint
:rawtypes -verbose -sourcepath c:\jtests X.java

but if you make Test a final class, eclipse also complains.

In the exact same contexts, eclipse has no hesitation in
flagging an assignment as being illegal.
