Subject Re: JDK 17 is now in Rampdown Phase One
Date Mon, 14 Jun 2021 17:06:24 GMT
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.
