> While running stress.org.apache.harmony.test.stress.gc.frag.Fragmentation test I noted
that emitter pass finishes with OutOfMemory excpetion raised (which was not handled in any
way :-(). Investigation showed the reason is creation of j.l.String objects during runtime
info resolution. I believe that proper solution should eliminate string objects creation at
all. If it is not possible then we should properly handle OutOfMemory.
> Thanks
