> gc_alloc() allocation path for finalizible object incorrect again.
> Fix for HARMONY-1588 added the flow. 'in_size' may have next to high bit set for object size. This indicates that the object has special features (is finalizible) and cannot be processed by fast path.
> Changing in_size to size in slow path fixes the problem.
> Bug is reproducible by java.lang.Runtime kernel test in interpreter mode. After the fix test passes for me.
