Your stack seems HUGE. Maybe that's cutting into how much heap is
available.

My comment was about your huge stack, i.e., -Xms1024M. It can't need
to be that big. And of course you can only make the heap so big. Not
sure if you can make it bigger that 1300M. You've tried?

All I could suggest is to try to have Eclipse in a state (fewer open
editors and such) where it's not already using so much heap space.
