Hi all.

I purchased Minecraft back in November for my son, who is a fan. The Windows 10 version runs fine, but the classic version doesn't. I seem to get some kind of weird Java errors when starting up, as seen here:

Exception in thread "main" java.lang.ExceptionInInitializerError

Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

Any ideas?

Sorry, this is just the part of the log from the launcher (game output), where can I find the entire report?

Pretty sure this is "special characters" in your windows user name.
