DecimalFormat documentation contains literal HTML character references

A DESCRIPTION OF THE PROBLEM :
https://docs.oracle.com/en/java/javase/16/docs/api/java.base/java/text/DecimalFormat.html

Contains multiple literal HTML character references instead of the respective character. Open the documentation in the browser and search for "&#" (without quotes).
A similar issue for the documentation of ServiceLoader was solved by using the U+XXXX notation, see JDK-8261306.

Slightly related (in case you want to fix that as well):
Javadoc for BigInteger also contains several times "<sup>" inside a "{@code ...}" inline tag, which would end up literally in the rendered output as well. However, that seems to affect only internal methods and is not visible in the publicly facing documentation.
