Why are those new methods added?

Why adding the custom serialization code? The string fields should be serializable by default, and the readObject & writeObject methods are unnecessary.

Once readObject & writeObject are removed, the final modifiers can be restored.

It is confusing to have 2 maps and they actually point to the same object if I am not mistaken.
More importantly, it leads to different init code paths. The patch is to fix the broken token calculation, but why leaving it half-fixed? The CDC code patch still calls the original constructor, which means CDC is still broken.
