That's much clearer.
However the method private final void addLast(Object node) is no
longer needed and could be inlined.
Sorry, I was confused by the addLast(); thought it was adding to the
new tree, rather than keeping track of the current one.

OK

There is only one condition check.
Surely the following have the same performance.
Positive:
if (node instanceof Timer) {
return node;
} else {
return super.addNodeToTree(node);
}
Negative:
if (!(node instanceof Timer)) {
return super.addNodeToTree(node);
} else {
return node;
}
I agree where there are multiple conditions, best to check the
cheapest first, but here there is only one check.
It's important for code to be readable.
