This defect only happens when the && is used such as
if (options != null && options.getSize() > 0)

Testcase
---------
package client;

// RUI Handler

//
//

handler testArrayNull type RUIhandler{onConstructionFunction = start, cssFile = "css/testBugs.css", title = "testArrayNull"}

    options String[] = ["coffee", "tea", "sugar"];

    function start()
    	if (options != null && options.getSize() > 0)
//    	if (options != null)
			printOptions(options);
		end
    end
    
    function printOptions(opts String[] in)
    	for (index int from 1 to opts.getSize() by 1)
    		syslib.writeStdout(opts[index]);
    	end
    end
end

-----
The generated js for if (options != null && options.getSize() > 0) is like
eze$Temp1 = ((egl.eglx.lang.EBoolean.ezeCast({eze$$value : this.options.appendElement(null), eze$$signature : "Teglx/lang/EList;"}) && ((this.options.getSize() > 0))));

In which append null to this.options is wrong
---------------

The RadioGroup widget suffers from this defect, can have a workaround to bypass it. But such kind of boolean statement is used frequently, so set the severity to major.
