This is no bug. It is 1 of the changeable settings that Eclipse includes to make the output more readable.
It can be changed by going to Windows --> Preferences --> Run/Debug --> Console and then unchecking “Limit Console Output” which is ON by default.
For more information and details about these settings visit:

This works on STS any version too. This would help printing complete console output.
