Weird isCurrentLanguageBidirectional() error

[AskHow1248]

Hello everybody,

      I've just started a new mod, and I'm getting a weird NullPointerException from net.minecraft.client.resources.LanguageManager.isCurrentLanguageBidirectional.  I haven't done anything, it seem to be something with the minecraft code.

 

Error report:

Thanks, but that's not it.

[AskHow1248]

I figured it out.  It happens if you have a pack.mcmeta file in your mpc/src/minecraft folder.

[FlameAtronach93]

Although it may be a bit late for this, I just had the same error loading a few months old frozen mod of mine trying to update it. Since it's modular, it's contained within its own project.

 

In general, said error occurs for any pack.mcmeta file in the classpath, in this case also in my mod's own eclipse project, not only {mcp_home}/src/Minecraft. Thanks to OP for pointing me into a particular direction.
