It was left there since the JFormattedTextField class is Serializable, and it is a kind of "public" API because it is mentioned in the serializable form of this class(I think so). See an example where I had to add the spec to the private fields via CSR: https://bugs.openjdk.org/browse/JDK-8252544 But the JFormattedTextField is part of the Swing where we intentionally added a statement "Serialized objects of this class will not be compatible with future Swing releases" So we can delete it but probably CSR will be needed, I am not sure. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15088#issuecomment-1659520041
