8247973: Javadoc incorrect for IdentityArrayList, IdentityLinkedList

[anupamdev20]

The documentation for following methods used equals() for object equality:

sun.awt.util.IdentityLinkedList#contains
sun.awt.util.IdentityArrayList#contains
sun.awt.util.IdentityArrayList#indexOf
sun.awt.util.IdentityArrayList#lastIndexOf
sun.awt.util.IdentityArrayList#remove(java.lang.Object)

I have updated the comments to use "==" operator for object equality. Kindly review the changes for the same.

I propose removing changes to HttpURLConnection.java from this PR. Both IdentityArrayList, IdentityLinkedList are in java.desktop module but HttpURLConnection is in java.base module. Submit a new issue to fix spelling errors in HttpURLConnection.java.

[aivanov-jdk]

Shall it have spaces on either side of ==?

Suggested change

	* {@code get(i)==o},
	* {@code get(i) == o},

I see IdentityLinkedList.java doesn't have spaces around == in this case. Yet in this case, probably {@code o == e} should not have the spaces too.

[aivanov-jdk]

An extra space.

Suggested change

	* if it is present. If this list does not contain the element, it is
	* if it is present. If this list does not contain the element, the list is

I think it adds clarification to what is unchanged.
