weka moa package missing classes

José Heitor
Hi,

I installed the MOA package in Weka, but when attempting to choose the
stream-type, I noticed that the list is empty:

What am I missing?

Thanks

Looks like the recent switch to Java 11 screwed up the MOA package for
some reason.
A colleague of mine confirmed that this is happening with OpenJDK
8/11, but works fine with Oracle's Java 8.
We'll be looking into fixing this for the next MOA release. In the
meantime, try using an Oracle Java 8 instead to launch Weka:

Cheers, Peter
