I think I might have this too:
I was just following the instructions in the new(ish) "How to Create a 
Map" wiki page 

I downloaded "wales.osm.pbf" dated 4th Oct from 

I ran  "java -jar splitter.jar wales.osm.pbf" as instructed on the "How 
to Create a Map" wiki page.

Result - out of Java heap space message (as follows):

Making SparseMultiMap

MAP occupancy: 973953

MAP occupancy: 26047

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

     at it.unimi.dsi.fastutil.longs.LongArrays.ensureCapacity(LongArrays.java:107)

     at it.unimi.dsi.fastutil.longs.LongArrayList.ensureCapacity(LongArrayList.java:202)

     at it.unimi.dsi.fastutil.longs.LongArrayList.size(LongArrayList.java:271)

(etc etc).

The program just hangs at that point, doesn't seem to do anything except 
generate a "progress" message every two minutes.
