[JDK 9] hs-rt forest fails to build?

[Severin Gehwolf]

Hi,

I'm trying to build an OpenJDK 9, hs-rt tree which fails to build for
me with:

jdk/src/java.logging/share/classes/sun/util/logging/internal/LoggingProviderImpl.java:33: error: cannot find symbol
import java.lang.System.LoggerFinder;
                       ^
  symbol:   class LoggerFinder
  location: class System

$ hg paths
default = http://hg.openjdk.java.net/jdk9/hs-rt/

Do I need to use a different tree these days? What am I missing?

Thanks,
Severin
