Hi all, I'm back to tring to build and run BookKeeper on java9 recently we added extensive usage of java.uti.Observable and Observer.
This classes have been deprecated in java9 and the build fails, because we forbid the usage of deprecated APIs. These classes are not used on client API but only on Bookie, so I think that in 4.6 we can switch them with other internal classes. Thoughts ? Enrico
