The fat java project was proposed by hotspot runtime team sometime 
during JDK 6 time frame. The main idea was to build the java launcher 
with the VM code so that all the VM code can be built without -fPIC (or 
-KPIC) flags. This could significantly reduce the relocation cost when 
the runtime linker/loader loads the libjvm.so library, also can improve 
the runtime performance such as lowering gc pause time etc.
