Re: errors trying to run autoweka from a Eclipse project

Hi,

which Java version are you running? Everything above Java 8 causes 
trouble. I had the same exception you got. Just changing the JRE from 11 
to 8 did the trick.

And as always, let me recommend to you ML-Plan (mlplan.org), which is a 
much better optimizer for WEKA than is auto-weka. Especially it has a 
much more efficient parallelization.

Best,
Felix
