[Junit-devel] Usage of generics in JUnit4: <? extends Object>

[Matthias S. <mat...@gm...>]

Hi all,

Looking through the JUnit4 sources, I stumbled upon the following code
fragment in JUnit4TestAdapter:

public JUnit4TestAdapter(Class<? extends Object> newTestClass) {
	this(newTestClass, JUnit4TestAdapterCache.getDefault());
}

Does using generics like this make any sense? EVERY class extends Object,
doesn't it? Is there any difference to

public JUnit4TestAdapter(Class newTestClass) {
	this(newTestClass, JUnit4TestAdapterCache.getDefault());
}

? Anything I am missing?

Regards,
Matt
