Create expected code depending on JDK version

closes #8445

[mbien]

please remove "solves issue 8445" from the commit message.

feel free to squash + rebase right away with the modifications since this is a smaller diff

I am going to update the PR title and link the PR to the issue. Btw we typically don't create issues for PRs if we plan to fix the problem anyway.

I know. The other email address was from the time when I joined GitHub. It is an email address I can no longer access.

the second commit has now the right email address I believe.

Whats left is to:

• add the simplification update UseSuperTypeTest for jdk 21 #8446 (comment) and then maybe fix the formattting too update UseSuperTypeTest for jdk 21 #8446 (comment) (space after ? and :)
• squash to one commit and update the message (update UseSuperTypeTest for jdk 21 #8446 (review))

squashing works like this:
inspect history:

$ git log --oneline
c4a0768b8 (HEAD -> issue8445) repair email address
3984a77b5 solves issue 8445
256edf4e9 (origin/master, master) Merge pull request #8604 from mbien/vue-css-prerequisite
...

lets say you want to squash the last two commits on top of that list and there is no merge commit in between

git rebase --autostash -i HEAD~2

this will open an editor with the following content

pick 3984a77b5 solves issue 8445                                        
pick c4a0768b8 repair email address                                     
                                                                        
# Rebase 256edf4e9..c4a0768b8 onto 256edf4e9 (2 commands)               
#                                                                       
# Commands:
... (more instructions)

By editing the second item on the list and changing pick into s and then saving+exiting the editor, git will squash the second line into the first (bottom up) and open another editor window, this window is for the commit message.

A well formatted commit message has a short description in the first line, then a blank line, then more info if needed.
for example for this change, I believe the PR title would be sufficient:

update UseSuperTypeTest for jdk 21

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
... (more info)

thats it, now check the log again and it should look like:

$ git log --oneline
eee9647b3 (HEAD -> issue8445) update UseSuperTypeTest for jdk 21
256edf4e9 (origin/master, master) Merge pull request #8604 from mbien/vue-css-prerequisite
219724b1d Add build-prerequisite flag to css.prep dep of javascript2.vue

Now in NetBeans, lets say you want to add something to the last commit without using the shell, simply use the commit action as usual, but check "Amend Last Commit" on the commit window. This will add the changes to the last commit, and also replace the commit message.

force push into the PR branch and it should be good. (see #8575 (comment))
