BrokenNullCheck

The null check is broken since it will throw a NullPointerException itself. It is likely that you used || instead of && or vice versa.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.basic.BrokenNullCheckRule
Example(s):



public String bar(String string) {
  // should be &&
	if (string!=null || !string.equals(""))
		return string;
  // should be ||
	if (string==null && string.equals(""))
		return string;
}
