java.lang.OutOfMemoryError: GC overhead limit exceeded
Download the new launcher from https://mojang.com/2013/06/minecraft-1-6-pre-release/ . With that you can assign more memory (Profile -> Options) to Minecraft. May help.

Any update on this issue ?

Increase the memory. Launcher -> Profile Editor -> Edit Profile -> JVM Arguments -> Change -Xmx1G to -Xmx2G (or higher)
