There are missing periods in the specification for the Font class:

lines 1612-1614 [1]
     * obtained. The {@code String} value of this property is then
     * interpreted as a {@code Font} object according to the
     * specification of {@code Font.decode(String)}

lines 1782-1783 [2]
     * The property value should be one of the forms accepted by
     * {@code Font.decode(String)}

These problems are found [3][4] during code review for JDK-8338411 in PR 21498 [5].
