EclEmma缺少的报道未突出显示

eclEmma的亮点没有显示任何遗漏的代码，但是报告显示了24条中有12条遗漏的指令。我很确定这是由于Coverage::doNotCall而引起的，但不确定其在寻找什么。我几乎可以肯定这不是构造函数，因为我有其他类似的类具有100％的覆盖率。有什么想法吗？

import java.util.function.BiConsumer;
import java.util.function.Supplier;
import java.util.stream.Stream;
public class Coverage {
private Coverage() {}
public static R collect(Stream stream,Supplier supplier,BiConsumer accumulator) {
return stream.sequential().collect(supplier,accumulator,Coverage::doNotCall);
}
static void doNotCall(@SuppressWarnings("unused") Object...args) {
throw new IllegalStateException();
}
}

try {
Coverage.doNotCall();
fail("Exception expected");
} catch (Exception e) {}
}
@Test

}
public static void assertPrivateConstructor(Class cls) {
try {
Constructor cOnstructor= cls.getDeclaredConstructor();
assertTrue("Constructor is not private",Modifier.isPrivate(constructor.getModifiers()));
constructor.setaccessible(true);
constructor.newInstance();
constructor.setaccessible(false);
} catch (NoSuchMethodException | invocationTargetException | IllegalaccessException
| InstantiationException e) {
throw new AssertionError(e);
}
}
}
