I've got the same problem now that intellij 2018.1 is out (no longer EAP)

[pabl0rg]

There are no localized versions of JavaCoreBundle.properties

https://github.com/JetBrains/intellij-community/tree/master/java/java-psi-api/src/messages

But one would think that the default is enough

[pabl0rg]

I opened an issue on the IJ youtrack and they closed it indicating that this should be handled by the plugin.

I think that duplicating core bundle messages inside plugin not a good idea but we can leave it as a workaround.
