LOADING FAILED!

I tried to restart the process, but I am getting the same error. Any ideas?

Running each stage manually by using java -cp wikibrain-withdeps-0.8.0.jar <StageMainClass> helped me pass this problem

I've spent half day to resolve the problem. For me the trick is to delete the "db" folder and restart the procedure.

Today i have found the issues.

The class org.wikibrain.utils.JvmUtils when is try to find the class have a limitation for the *.jar file SIZE ( 8 Megabytes), so the jar containing the RawPage class (wikibrain.withdeps-X.X.X.jar) is skipped and the class is not found.

To jump the problem you must add to the classpath the wikibrain-core-X.X.X.jar file.

To obtain the wikibrain-core-0.9.1.jar file you need to rebuild the maven project. After you have build the jar you add it into the wikibrain dictionary folder.

An example for version 0.9.1 -> Load the GUI manually adding the core.jar to the classpath. In the folder of wikibrain dictionary call

java -cp wikibrain-withdeps-0.9.1.jar:wikibrain-core-0.9.1.jar -Xmx8000M org.wikibrain.GuiLoader

This solve the issues for RawPage not found.
