Streams declared in constructors throw java.lang.AssertionError exception

[yiming-tang-cs]

#68
When I test this:

package q;

import java.util.ArrayList;
import java.util.Collection;

public class Test {
	
	Test(){
		Collection<String> col = new ArrayList<>();

		long count = col.stream().distinct().count();
	}
	
	void p() {

	}
	
}

an exception is thrown:

It doesn't seem to matter if the stream is a field or local variable.

I wonder if we have a test case for this.
