PsiTreeUtil.getParentOfType () bug, or ?

Here is the source code. You can compare it with your version.

public static PsiElement getParentOfType(PsiElement element, Class[]
classes, boolean strict) {
if (strict) {
element = element.getParent();
}

while (element != null) {
for (int i = 0; i < classes.length; i++) {
Class aClass = classes+;
if (aClass.isInstance(element)) return element;
}
element = element.getParent();
}

return element;
}

They behave differently on this piece of code (the caret is in a
comment line) :
