Hi All, I was reading the article below and I was wondering how did one manage to block all I/O calls given that there is no byte code instruction for I/O in java instead all the I/O calls in java will go through *invokevirtual *byte code instruction. But this can call a C function that just add two numbers right. so how can one block all I/O calls?
