The Inet4Address and Inet6Address classes were added in 1.4, which is correctly indicated by the class-level @since javadoc tag. There are several other method-level @since javadoc tags that indicate that the method was added in a release prior to 1.4. These are clearly incorrect.

jdk/src/java.base/share/classes/java/net/Inet4Address.java:162
Containing element : java.net.Inet4Address, inner element : java.net.Inet4Address.isMulticastAddress()
The version of containing element is greater than the version of the inner one : 1.4 >= 1.1

jdk/src/java.base/share/classes/java/net/Inet4Address.java:327
Containing element : java.net.Inet4Address, inner element : java.net.Inet4Address.getHostAddress()
The version of containing element is greater than the version of the inner one : 1.4 >= 1.0.2

jdk/src/java.base/share/classes/java/net/Inet6Address.java:689
Containing element : java.net.Inet6Address, inner element : java.net.Inet6Address.isMulticastAddress()
The version of containing element is greater than the version of the inner one : 1.4 >= 1.1

There are a number of superfluous method-level '@since 1.4' javadoc. These are not needed since there is a class-level @since javadoc tag.
