Unfortunately yes. Hence my focus has been primarily on profiling the code path
to start the solr system and hence to stress this. I agree with your concern
about having static objects being live (after their intended use ) affecting
memory but may be that could be grouped under ResourceMap but recreating the
Pattern object , internally with all the NFA graph compilation would be better
to be optimized as against the memory constraint.
