Maybe if you post the log itself staff or people who know a lot about java can be sure what the problem is.
heap size too large. You probably need to upgrade your PC for more ram or close down some applications when using the bot.
Couple tips: 1. Reboot your PC. 2. Post specs (including OS), max heapsize = most memory that can be allocated to the JVM. Too little RAM could be an issue (unless I am misinterpreting)? 3. Allocate a custom max heapsize to the client, you can google how to do this.
