[1.7.2][fixed]Crash upon loading a world

[tehftw]

This error was fixed by reinstalling Java, both JRE and JDK. I also installed Gradle, if reinstalling this doesn't work.

 

After building the code in Eclipse and trying to start a new world, everything crashes.

For some reason a Superflat doesn't crash, so I suspect it's a problem with world generator.

This field (WeightedRandom$Item.itemWeight) is marked as protected in the source I have from MCP (both alpha and beta), so I went to see what Forge changes in functionality that it accesses that field. Weirdly enough, it is marked public in my Forge dev workspace I got through Gradle. I wanted to help you, but got more confused instead

[robotbrain]

I'm getting this too

This error was fixed by reinstalling Java, both JRE and JDK.

 

If this still doesn't work for you, know that I also installed gradle.
