 and is detecting a feature on the buildbots which you don't have. We could
 then look into restricting the features used by default.

 I tried that, but the build fails at step 921.  It seems to use jdk-12.0.1
 regardless of what JAVA_HOME is set to.  I tried jdk1.8.0_211 and also
 unsetting JAVA_HOME.

 The last 50 lines of the log is attached.
