Permgen space problem


Recommended Posts

Sup guys

Ive been playing around with tekkit for a while now and decided to add more mods, problem is java only dedicates 87mb to permgen space and with many mods you quickly run out of this room

now i can run minecraft with special commands through a .bat file and increase the permgen space and to automaticly cleanup the crap in permgen space

Yet this doesnt work with tekkit since i cant find a way to run tekkit with special commands like:

-XX:MaxPermSize=128M, -XX:+CMSClassUnloadingEnabled,

-XX:+CMSPermGenSweepingEnabled and -Xms2048m -Xmx4096m ofc

so how exactly do i run my tekkit client with those commands

I found it was pretty easy to unzip the launcher jar file, use jd-gui to decompile org.spoutcraft.launcher.Main and save the source to Main.java, then add a line such as


in the reboot method. Then recompile using jdk 1.6 from the top level of the folder the jar file was unzipped into.

e.g. javac org/spoutcraft/launcher/Main.java

I'd post a jar file but that's against forum rules without admin permission. Hopefully this tip will hold people over until they release the new launcher.
