----------------------------------------------------------

There is another small issue related with this bug.  
Methods like *FieldCacheImpl.GetStringIndex* , *FieldCacheImpl.GetStrings* etc. get  ??"Object
reference not set to an instance of an object"??  exception when *TestSort.TestParallelMultiSort*
is executed with 10-20 threads in parallel. 
Making *FieldCacheImpl.Init* atomic solves the problem. 

I committed the patch.
