| ok, this isn't a jenkins bug.
| The ALPN APIs have been backported from Java 9 to OpenJDK 8u251/8u252. Therefore, since OpenJDK 8u251/8u252 there is no more need for the Jetty ALPN boot jar provided by this project. |

So, I had updated to jenkins 2.233 – and things were fine. Then java updated to 8u252 (which is incompatible w/ the jetty alpn, as it integrated it), but jenkins the service wasn't restarted. Then I upgraded to jenkins 2.234 – and things exploded. But, the problem wasn't jenkins, it's just that I hadn't restarted it since the java upgrade, which is why downgrading didn't fix the problem. Solution: remove ALPN from the path, as it's no longer needed. |
