out of memory alhtough using cyclic output buffer

see screenshot.
I use cyclic buffer of 1024kb, yet running the app that produces very much output (probably System.out in a while(true) loop) IDEA freezes with OOm.

... and yes, I do know that System.out in a while(true) loop is not a good IDEA - but I did not write that code ;)


Bye,
