java.lang.OutOfMemoryError even though plenty of

Question

I am trying to read a 2.5GB txt file into my application. I am running Win7 x64 and have 43GB of mem available (out of 64GB). I tried playing around with -Xmx -XX:MaxParmS

Answer 1

You should look into the -Xmsn option for the java command.

It specifies the initial size of the memory allocation pool.

Edit: I see you've already done that.
