Additionally, more as a FYI - we have started to receive user reports 
that the new security manager deprecation WARNING messages on System.err 
are impacting some of their existing build scripts

I had a look at this one in more detail. The failure is in one of our 
javadoc related tests[1]. After looking into the details, this 
appeared to be a genuine regression. So I raised this in the 
javadoc-dev mailing list[2]. In that discussion it has been 
acknowledged as an intentional change in this version of the JDK and 
not a bug. It did however expose another bug for which a new JBS issue 
has been created[3]


The Ant project needs to do certain changes to take into account both 
the security manager warnings and this change in behaviour of javadoc 
tool. I'll create a separate Ant dev mailing list thread for that 
tomorrow.

Hello Rory,

This JDK 17 EA build 26, has caused at least one regression in our 
testsuite. It relates to the new WARNING message that gets printed out 
to System.err, when something at runtime sets the security manager. 
Given the nature of the test that's failing, fixing it is trivial for 
us, so I'll probably do that tomorrow. However, I would have liked a 
bit more easy debuggability around what piece of code is setting the 
security manager. So I've raised this as a question in security-dev 
mailing list of JDK[1].


Additionally, there's one other test that failed with this build. I 
haven't yet found the time to look into that one in a bit more detail. 
I plan to do that tomorrow and send an update if it turns out to be an 
issue in JDK.
