The problematic code was removed in the current repo by [JDK-8234596](https://bugs.openjdk.org/browse/JDK-8234596), however that change was large, and required a CSR. I feel that it would be too risky and cumbersome to backport those changes to jdk11 (and ultimately jdk8 as well), so I'd like to propose this change as a new change to jdk11 rather than via the usual backport process.

Hi @backwaterred, in JDK-Updates projects you must not issue /integrate only when a PR is ready. You also need to get maintainer approval by putting the jdk11u-fix-request label in the JBS issue, along with some comment why you're requesting the backport, its testing etc., and waiting for the approval label. This is also true for net new items that aren't a downport of some existing fix as in your case. So, please add the JBS ceremony. Thx.
