Harmony VM doesn't have hotspot mode. Interpreting mode never switches to JIT 
so interpreter is really intended for debugging and possibly for quick 
porting to other architectures (you need to write small portions of assembly 
for calling native methods). Interpreting the code is definitely slow 
compared to compiling it.
