JDK 11 problems in BOM at HEAD

At least I think that's what's happening here. Investigating.

confirmed same code passes on JDK 8.

It's possible this is a result of mixing JDK 11 with a JDK 8 classpath or some such. I will reverify in a clean JDK 11.

This appear to be an issue in pure JDK 11 environment, perhaps in part or full due to the protobuf issue:

protocolbuffers/protobuf#7827

The JDK 11 build succeeds now.
