Review Comment:
   While `-Xmx2500m` might be still useful to allocate enough heap on machine 
with memory less than 5GB (because the default maximum heap of JVM is capped at 
half of the machine's memory IIRC), we can not practically use such a small 
machine for Bigtop development. I think dropping `-Xmx` too should be ok.
