Regression after April Java 17 Update (mime types)

[Langer, Christoph]

Hi Bernd,

I just noticed your report regarding the regression after JDK-8273655. I'm directing this communication to jdk-updates-dev now as it seems more appropriate.

I assume with release notes you're referring to the Oracle 17.0.3 release notes? This change, if you look closely at the backports, was only brought to OpenJDK 17.0.3 and it will hit the OpenJDK 11u update 11.0.16 in July. So, it would not be reflected in Oracle release notes. The best you can get for OpenJDK 17.0.3 release notes is [0], to my knowledge.

Do you have some more information regarding the incompatibility? What I'm understanding is that this backport unveils a problem with Apache VFS? Do you have a bug link for that one? If it's just uncovering a bug in another 3rd party software, I assume it doesn't merit a backout, though.

Best regards
Christoph
