Splitter application error

So I am trying to split a .osm.pbf file (158MB file), i always get this error:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

It does generate the following files:
areas.list
areas.poly
densities-out.txt
template.args

Does this means that my PC is not powerful enough (16gb of ram) and that i just should stop trying?
