I am trying to launch a forge server (using forge -1.12.2-14.23.5.2854). i had just installed the forge server jar and when trying to open it with java(TM) the console either freezes and stops doing anything OR i get a spam of java.lang.OutofMemoryError:Heap something or other. any idea how or what im suppose to do to fix this? the console itself says "memory used 191mb (22% free) avg ticks 0.000ms"
